Top 10 Thinking Traps Exposed — How to Foolproof Your Mind, Part II

Luciano Passuello — Wed, 08 Jul 2009 12:28:15 +0000

In the first part of this article, we focused on 5 traps that hinder our ability to think rationally. As a quick recap, we discussed:

The Anchoring Trap: Over-Relying on First Thoughts
The Status Quo Trap: Keeping on Keeping On
The Sunk Cost Trap: Protecting Earlier Choices
The Confirmation Trap: Seeing What You Want to See
The Incomplete Information Trap: Review Your Assumptions

Now it’s time to complete the list and expose the remaining 5 dangerous traps to be avoided. Let’s dive right in.

6. The Conformity Trap: Everybody Else Is Doing It

In a series of experiments, researchers asked students in a classroom a series of very simple questions and, sure enough, most of them got the answers right. In another group, they asked the same questions but this time there were actors posing as students, purposefully pushing wrong answers. This time around, many more students provided wrong answers based on the leads from the researchers’ assistants.

This “herd instinct” exists — to different degrees — in all of us. Even if we hate to admit it, other people’s actions do heavily influence ours. We fear looking dumb: failing along with many people is frequently not considered a big deal, but when we fail alone we must take all the heat ourselves. There’s always peer pressure to adopt the behaviors of the groups we’re in.

This tendency to conform is notoriously exploited in advertising. Businesses often sell us products not based on their features, but by showing how popular they are: since others are buying it in droves, why would we not join them?

Conformity is also one of the main reasons why once a book makes into a well-known best-sellers list, it tends to “lock in” and continue there for a long time. People like to consume what “everybody else” is consuming.

What can you do about it?

Discount the influence of others. When analyzing information, shield yourself from others’ opinions — at least at first. This is the best way to decide without being subconsciously swayed by popular opinions.
Beware “social proof”. Always raise a flag when someone tries to convince you arguing primarily on the popularity of a choice, instead of on its merit.
Be courageous. Be willing to overcome obstacles and defend your viewpoints, despite their unpopularity. Don’t be afraid to point out that the Emperor wears no clothes.

7. The Illusion of Control Trap: Shooting in the Dark

Have you noticed that the vast majority of lotto players pick their own numbers instead of using the sometimes available ‘auto-pick’ option (where the point of sales terminal chooses the numbers for you)? We all know that however the numbers are chosen doesn’t change the chance of winning, so why the strong preference for picking our own numbers?

Curiously, even in situations we clearly can’t control, we still tend to irrationally believe that we can somehow influence results. We just love to feel in control.

Of course, it’s always easier to illustrate this trap with chance games, but the tendency to overestimate our personal control of events influences every aspect of our daily lives.

Unfortunately, contrary to the lottery example above, the outcomes of our decisions are usually complex and interconnected. It’s hard to assess to what extent we’re responsible for the results we get. While some of the outcomes can be traced back to our own choices, a part of them will surely remain just as well out of our direct control.

What can you do about it?

Understand that randomness is part and parcel of life. Although it may be hard to fathom or even admit it, some things are just random — in the sense that they don’t depend on your effort at all. Accept responsibility for the things you can influence, but know that for many others there is not much you can do. Better than assuming or expecting that every event is under your control is to consciously choose how you respond to them.
Beware of superstitions. Consider how much of your decisions are based on things you cannot really explain. Make those unknowns explicit and put them under scrutiny — instead of pretending you can control them.

8. The Coincidence Trap: We Suck at Probabilities

John Riley is a legend. He won a one-in-a-million-chance lottery… twice! That makes it a 1-in-a-trillion event — which means that the lottery is rigged or maybe John must have been singled out by Lady Luck, right?

Well, not really. Let’s try a little math: If, throughout the years, 1000 lottery winners keep playing at least 100 times attempting the “miracle” of winning it once more, that adds up to a non-negligible chance of 10% that someone will make it.

This means that the “miracle” is not only possible but — given enough attempts — its likelihood increases to a point of becoming almost inevitable.

Another classic example: it takes a group of just 23 people to make it more likely than not that two of them share the same birthday (day and month).

That’s how unintuitive probabilities are.

What can you do about it?

Don’t over-rely on gut estimates. While useful many times, gut estimates will sometimes be way off the mark. Make sure you properly discount their importance or that you understand the ramifications of trusting them.
Beware of “after the fact” probabilities. One thing is the probability of someone having won the lottery twice — looking at it in retrospect. Another completely different thing is that a particular person — chosen before the outcome — wins it: that would indeed qualify as a one-in-a-trillion event — and would make anyone seriously doubt the legitimacy of that lottery.

9. The Recall Trap: Not All Memories Are Created Equal

What’s your best guess for the probability of a randomly selected flight ending in a fatal crash? While many people grossly overestimate it, MIT studies show that in reality these fatal accidents happen at a rate of only 1 in 10,000,000.

The fact that people suck at estimating probabilities explains only partially this tendency to mis-estimate: if you ask the same question right after a major airplane accident, be prepared for even more biased assessments.

What happens is we analyze information based on experience, on what we can remember from it. Because of that, we’re overly influenced by events that stand out from others, such as those with highly dramatic impact or very recent ones. The more “special” an event is, the greater the potential to distort our thinking. Of course, no one ever bothers about the other 9,999,999 planes that arrive safely at their destinations — so there’s nothing more natural than forgetting about them.

What can you do about it?

Get hard data. As usual, don’t rely on your memory if you don’t have to. Use it, of course, but always endeavor to find data that confirms or discounts your recollection as soon as possible.
Be aware of your emotions. When analyzing information, try to emotionally isolate yourself from it, at least temporarily. If you’re analyzing an event, pretend it happened a long time ago or that it happened to someone else unrelated to you. Likewise, if asking for opinions, find people who are not emotionally involved with them or their consequences.
Beware the media. The media is notorious for exaggerating the importance of certain events while conveniently neglecting others. Always evaluate information on its relevance and accuracy, and not on how much exposure it gets.

10. The Superiority Trap: The Average is Above Average

A study surveyed drivers asking them to compare their driving skills to other people in the experiment. Almost all the participants (93%!) rated themselves as ‘above average’.

With few exceptions, people have much inflated views of themselves. They overestimate their skills and capabilities, leading to many errors in judgment.

And this is the reason I decided to close this article with this particular thinking trap. After making ourselves aware of these many thinking traps, we may now become susceptible to falling into a new one: the belief that we’re now immune to them.

Of course, the first step to avoid thinking traps is awareness and constant vigilance, but beware: it’s much, much easier to notice others falling into these traps than us.

What can you do about it?

Be humble. Always remember that everyone has blind spots (yes, that includes me and you)!
Surround yourself with honest people. If we all have blind spots, nothing better than having honest people around us to point them out to us.
Don’t go overboard. These ‘thinking traps’ are inherent parts of us: they make us human. Applying rigor and rational thinking to our decisions is important, but that doesn’t mean that intuition has completely lost its place. Don’t get me wrong: I still think that knowing about our own thinking traps is very useful — just don’t get too worked up about them.

Further Resources

These ten thinking traps barely scratch the surface when it comes to how our thinking can be biased. Wikipedia’s list of cognitive biases has more than 100 of these traps, making it a hard-to-beat starting point for further learning.

The references for the studies that back up the data in this article can be found on the respective articles on Wikipedia, as well as on the book Smart Choices. That’s a marvelous book about decision making, and one which I highly recommend. Another great book to check out is Thomas Gilovich’s How We Know What Isn’t So.

I hope you enjoyed the article. And just in case you missed it, here’s part 1, where you can find the first 5 thinking traps we started with.

Top 10 Thinking Traps Exposed — How to Foolproof Your Mind, Part I

Luciano Passuello — Wed, 24 Jun 2009 13:44:21 +0000

Our minds set up many traps for us. Unless we’re aware of them, these traps can seriously hinder our ability to think rationally, leading us to bad reasoning and making stupid decisions. Features of our minds that are meant to help us may, eventually, get us into trouble.

Here are the first 5 of the most harmful of these traps and how to avoid each one of them.

1. The Anchoring Trap: Over-Relying on First Thoughts

“Is the population of Turkey greater than 35 million? What’s your best estimate?” Researchers asked this question to a group of people, and the estimates were seldom too far off 35 million. The same question was posed to a second group, but this time using 100 million as the starting point. Although both figures were arbitrary, the estimates from the ‘100 million’ group were, without fail, concomitantly higher than those in the ‘35 million’ group. (for the curious, here’s the answer.)

Lesson: Your starting point can heavily bias your thinking: initial impressions, ideas, estimates or data “anchor” subsequent thoughts.

This trap is particularly dangerous as it’s deliberately used in many occasions, such as by experienced salesmen, who will show you a higher-priced item first, “anchoring” that price in your mind, for example.

What can you do about it?

Always view a problem from different perspectives. Avoid being stuck with a single starting point. Work on your problem statement before going down a solution path.
Think on your own before consulting others. Get as much data as possible and explore some conclusions by yourself before getting influenced by other people’s anchors.
Seek information from a wide variety of sources. Get many opinions and broaden your frame of reference. Avoid being limited to a single point of view.

2. The Status Quo Trap: Keeping on Keeping On

In one experiment a group of people were randomly given one of two gifts — half received a decorated mug, the other half a large Swiss chocolate bar. They were then told that they could effortlessly exchange one gift for the other. Logic tells us that about half of people would not get the gift they prefered and would hence exchange it, but in fact only 10% did!

We tend to repeat established behaviors, unless we are given the right incentives to entice us to change them. The status quo automatically has an advantage over every other alternative.

What can you do about it?

Consider the status quo as just another alternative. Don’t get caught in the ‘current vs. others’ mindset. Ask yourself if you would choose your current situation if it weren’t the status quo.
Know your objectives. Be explicit about them and evaluate objectively if the current state of affairs serves them well.
Avoid exaggerating switching costs. They frequently are not as bad as we tend to assume.

3. The Sunk Cost Trap: Protecting Earlier Choices

You pre-ordered a non-refundable ticket to a basketball game. On the night of the game, you’re tired and there’s a blizzard raging outside. You regret the fact that you bought the ticket because, frankly, you would prefer to stay at home, light up your fireplace and comfortably watch the game on TV. What would you do?

It may be hard to admit, but staying at home is the best choice here. The money for the ticket is already gone regardless of the alternative you choose: it’s a sunk cost, and it shouldn’t influence your decision.

(This example is from an earlier article which focuses entirely on the sunk cost effect. Check it out if you want to know more.)

What can you do about it?

Be OK with making mistakes. Examine why admitting to earlier mistakes distresses you. Nobody is immune to errors, so you shouldn’t make a big deal out of it — just make sure you learn from them!
Listen to people who were not involved in the earlier decisions. Find people who are not emotionally committed to past decisions and ask their opinion.
Focus on your goals. We make decisions in order to reach goals. Don’t become attached to the particular series of steps you took towards that goal; always consider how you can better fulfill that goal from now on.

4. The Confirmation Trap: Seeing What You Want to See

You feel the stock market will be going down and that now may be a good time to sell your stock. Just to be reassured of your hunch, you call a friend that has just sold all her stock to find out her reasons.

Congratulations, you have just fallen into the Confirmation Trap: looking for information that will most likely support your initial point of view — while conveniently avoiding information that challenges it.

This confirmation bias affects not only where you go to collect evidence, but also how you interpret the data: we are much less critical of arguments that support our initial ideas and much more resistant to arguments against them.

No matter how neutral we think we are when first tackling a decision, our brains always decide — intuitively — on an alternative right away, making us subject to this trap virtually at all times.

What can you do about it?

Expose yourself to conflicting information. Examine all evidence with equal rigor. Don’t be soft on disconfirmatory evidence. Know what you are about: Searching for alternatives or looking for reassurance!
Get a devil’s advocate. Find someone you respect to argue against the decision you’re contemplating making. If you can’t find one, build the counterarguments yourself. Always consider the other positions with an open mind (taking into account the other mind traps we are discussing here, by the way).
Don’t ask leading questions. When asking for advice, make neutral questions to avoid people merely confirming your biases. “What should I do with my stocks?” works better than “Should I sell my stocks today?”

5. The Incomplete Information Trap: Review Your Assumptions

Harry is an introverted guy. We know that he is either a librarian or a salesman. Which one do you think he most probably is?

Of course, we may be tempted to think he’s almost certainly a librarian. Haven’t we been conditioned to think of salesmen as having outgoing, if not pushy, personalities? Too bad this reasoning may be dead wrong (or at least incomplete).

This conclusion neglects the fact that salesmen outnumber librarians about 100 to 1. Before you even consider Harry’s character traits, you should have assigned only a 1% chance that he’s a librarian. (That means that even if all librarians are introverted, all it takes is 1% of introverts among the salesmen to make the chances higher for Harry being a salesman.)

That’s just one example of how overlooking a simple data element can make our intuitions go completely astray. We keep mental images — simplifications of reality — that make we jump to conclusions before questioning assumptions or checking whether we have enough information.

What can you do about it?

Make your assumptions explicit. Don’t take a problem statement as it is. Keep in mind that for every problem you’re using implicit information — your assumptions. It’s usually not hard to check the validity of assumptions, but first you need to know what they are.
Always favor hard data over mental simplifications. Our preconceptions — such as stereotypes — can be useful in many situations, but we should always be careful to not over-rely on them. When given the choice, always prefer hard data.

Sharpen Your Critical Thinking With E-Prime

Luciano Passuello — Tue, 24 Feb 2009 13:22:30 +0000

Have you ever heard of E-Prime? Critical thinkers use it as a tool to write, speak and think more clearly and accurately. Learn how you can use it to sharpen your critical thinking abilities, avoid mental traps and become a better thinker.

An E-Prime Primer

The term E-Prime (short for English Prime) refers to a dialect that completely removes the verb ‘to be’ in all its forms from the English language.

It turns out that the use of the verb to be alone may respond for a great deal of faulty reasoning we commonly find. Intentionally or not, people tend to abuse that verb, perpetuating a way of thinking that hinders proper critical thinking.

E-Prime helps bring awareness to how we use language and how it impacts thinking. It serves as a practical starting point for a less dogmatic way of thinking, and it goes much further than merely finding word substitutions for the missing ‘to be’s.

Now, consider for a minute how much you use the verb to be. Eliminating it from language means you can’t say sentences such as “The sky is blue”, “John is smart” or even the simplest “I’m hungry”. In fact, by my own reckoning, I estimate that about half of the phrases we say contain to be in some form.

Although we can easily reword “I’m hungry” as “I feel hungry”, in many cases the E-Prime conversion shows itself far from trivial. Before jumping right into using E-Prime, we must ponder the reasons to learn it and the benefits we may gain from not using the verb to be. Why bother with E-Prime at all?

9 Ways E-Prime Can Help You Become a Better Thinker

1. It Exposes Opinions Disguised as Facts

Consider “Beethoven is the best composer ever”, or “This is a stupid idea”. These sentences illustrate how we express opinions as if they represented established facts. Getting rid of to be helps us remember that much of what we say represents, as a matter of fact, just opinions. Consider the E-Prime alternatives for those sentences: “I like Beethoven’s compositions best”, and “I utterly dislike this idea!”.

2. It Promotes Higher Accuracy and Exposes Hidden Assumptions

Refraining from using the verb to be may require you provide much more detail than usual. For instance, when rewording “Jack is smart”, you could end up with “Jack scored 140 on his IQ test” or maybe “Jack earns money without working” — depending on your definition of ’smart’. E-Prime encourages you to detail ambiguous words (such as ’smart’), helping expose any hidden assumptions behind them.

3. It Reveals the (Fallible) Observer

Consider the statement “The Earth is round”. Notice how the verb to be carries with it an intellectual momentum of completeness, finality, and time-independence. It sounds like an absolute, immutable truth, doesn’t it? Yes, it does… exactly like the statement “The Earth is flat” just a few hundred years ago.

The alternative E-Prime construct “The Earth looks round” shows that an observer exists — an observer that simply perceives the Earth as round — and that this observer may have flaws in perception. E-Prime brings back a certain ‘humbleness’ in language, getting rid of the “God Mode” in speech and reminding us we make mistakes.

4. It Avoids Premature Judging and Labeling

E-Prime discourages abstractions that lead to labeling and prejudice. Contrast “Mary is Christian” with “Mary believes in the existence of Christ”. While these two sentences have the same meaning, the E-prime version avoids any prejudices associated with the label ‘Christian’.

As a side note, labeling happens not only when dealing with other people, but with ourselves. If you find yourself saying “I’m a pig!”, try the E-Prime “I eat like a pig”, or, going further, “I ate twice as much as I usually do at dinner”.

5. It Brings the Role Players Back

When using E-Prime, you’ll soon notice that using passive voice can get very hard. Although this looks limiting at first, I can tell that you’ll hardly miss passive voice once you get used to it.

When you can’t resort to uncompromising statements such as “Mistakes were made”, you’ll have to rephrase it as, say, “Steve made a mistake”. Or, if you really don’t know (or don’t want to expose) the doer, you could use “Someone in this room made a mistake”. This latter statement still rises as a superior alternative to the former, since at least you explicitly point out that exists a doer behind the action.

6. It Makes Language More Colorful

Before using it, I believed that E-Prime would make language more convoluted, duller and less personal.

Granted, your language may suffer if you have just taken your first steps in E-Prime (like me). However, with a little bit of practice, you’ll notice that E-Prime provides an excellent opportunity for a much more vibrant and vigorous way of writing. (Or do you think I didn’t consider the verb to be before choosing provides in the previous sentence?)

E-Prime promotes not only richer verb diversity but also improvements in style, too. If forced to rewrite common sentences such as “Sarah is wealthy”, one can come up with many stylistically superior variations instead, such as “Sarah possesses many riches”.

7. It Stimulates Debate

“You’re wrong”! In E-Prime, this easily turns into “I don’t see it that way”. This style of communication immediately opens the possibility for debate, without the need to overturn the other person’s statements first. Declarations such as “I liked the movie” invite healthy discussion and the sharing of different opinions — much more enticingly than the usual “The movie was good”.

In E-Prime, we deal with perceptions, not absolute truths. And perceptions never override each other, and thus can never clash.

8. It Improves Creativity

E-Prime can also help in the realm of creativity and problem solving. Firstly, it dissolves notions such as “There is no solution!”, turning them into superior choices such as “I haven’t found any solutions (yet)”.

More than that, E-Prime helps you overcome generalizations and get to the facts more objectively, enabling you to find solutions initially overlooked. After some E-Prime reframing, “The customer is stupid!” could become “The customer won’t buy our product even though it costs less”. The latter makes a much better starting point for coming up with solutions than the former.

9. It Exercises Your Brain

If for nothing else, try E-Prime for an excellent brain workout! Trust me, you’ll never know how challenging it gets if you don’t try it. Learning E-Prime feels exactly like learning a new language, except that instead of learning new constructs, you must ‘unlearn’ part of what you already know. It will fire up your neurons!

Parting Words

Before I finish this, let me say that E-Prime does not come without its imperfections. Many people expressed valid criticism, which I agree with in many ways.

Granted, E-Prime does not immunize you from falling into the traps of thinking I described. You can still state opinions as facts in E-Prime. You can still lie, deceive and express prejudice. Worse yet, you can still continue using to be implicitly, hiding the actual words but keeping it in spirit.

Also, for many people, E-Prime goes too far in eliminating to be altogether. In fact, many instances of to be don’t present any problems. For that reason, some have decided to adopt ‘lighter’ versions of E-Prime that allow some particular usages of to be.

For me, E-Prime symbolizes more a way of thinking than a mere grammar restriction. Its main goal consists of bringing a higher awareness on how language affects our thoughts — and not of enforcing a strict, blind limitation to language. It has more to do with developing new habits of thinking than with adhering to it rigidly.

Although I don’t plan to abandon regular English in favor of E-Prime, I still believe that everyone can benefit from trying it, if only for a while. Make a short trial and see for yourself how it affects your thinking and your awareness of your and other people’s language.

Additional Resources

I barely scratched the surface when it comes to E-Prime. If you want to get practical tips on forming sentences in E-Prime, or if you want to understand E-Prime implications more deeply, the Internet has many resources for you. Let me point out some of the best I’ve found:

Wikipedia E-Prime Page. As usual, Wikipedia makes a great starting point for research. Contains several links to jumpstart your E-Prime quest.
E-Prime Tutorial. This tutorial shows extensive practical tips on how to actually write in E-Prime.
Working with E-Prime: Some Practical Notes. Article by David Bourland, Jr., the creator of E-Prime (website no longer available, found via The Internet Archive.)
E-Prime: The Spirit and the Letter. Discussion about the ’spirit’ of E-Prime, contrasting the strict E-Prime usage with just using its concepts in a not-so-radical way.
The E-Primer. Online tool to check texts for “E-Primeness”. Highlights all instances of the verb to be in your text.

What Do You Think?

This article comes as my first attempt to publish an article in E-Prime. As I took my first steps in E-Prime only a couple of weeks ago, let me know if the article sounds too awkward. Thank you!

P.S.: How about leaving your comments in E-Prime?
