This post is part of the 📖 Mental Models series.


Today, I am reading the 13th mental model Peer Review Your Perspectives from Eye-Opening Problem-Solving chapter of the book Mental Models written by Author Peter Hollins.

TL;DR! 💬

Mental Models are like giving a treasure map to someone lost in the woods. They provide instant understanding, context, and most importantly, a path to the end destination. Now imagine having such a map for all problems and decisions in your life.

In this book Mental Models, author Peter Hollins discuss 30 mental models that billionaires/CEOs, Olympic athletes, and scientists use to think differently and avoid mistakes.

Battle information overwhelm, focus on what really matters, and make complex decisions with speed and confidence.


Yesterday, I finished reading the 12th mental model Think With System 2.

Chapter #3: Eye-Opening Problem-Solving

Mental Model #13:

Peer Review Your Perspectives

Use to understand the consensus view and why you might differ.

As the name implies, a peer review evaluates your work conducted by other people in your field. Other like-minded colleagues within your area of study or expertise review your work and offer feedback and suggestions before submission.

Peer reviews aim to guard against inaccuracies or omissions in a final work and offer alternative viewpoints that could help make the results more transparent, relevant, or precise.

A specific application of this mental model is called triangulation. Officially, triangulation of information requires collecting and verifying information from at least two different sources. Optimally, there are many more.


Key Takeaways

  • Thinking and solving in a vacuum will never work because if you didn’t experience it firsthand, it wouldn’t make sense to you.

  • Subjecting your perspectives and ideas to peer review and triangulation increases your legitimacy and authenticity.

Summary

  • Peer Review Your Perspectives. Many of the ways we fail at solving problems are related to our inability to look at other perspectives. We should be continually checking our perspectives through triangulation against those of others.

That’s it for today. Tomorrow, we will read the 14th mental model Find Your Own Flaws, use to scrutinize yourself before others can.

What mental models we've learned so far?
  1. Address “Important”; Ignore “Urgent”

    Identify and address important tasks, ignore urgent tasks. Delegate important but non-urgent task and delete not important and not urgent tasks.

  2. Visualize All the Dominoes

    Don’t stop your analysis once the most obvious situations are articulated. Consider as many long-term possible ramifications as you can. Think twice about what you’re doing, and it helps to eliminate rash decisions.

  3. Make Reversible Decisions

    If you want to make the best decision possible, you can go ahead and use reversible decisions to learn exactly what you need to know.

  4. Seek “Satisfaction

    We need far fewer things than we originally thought and that our desires are masquerading as needs. Use Seek “Satisfaction” to achieve your priorities and ignore what doesn’t matter by creating a default choice.

  5. Stay Within 40-70%

    Utilize this mental model by intentionally consuming less information and even overgeneralizing — this means not looking at the subtleties of your options.

  6. Minimize Regret

    Minimize Regret. Jeff Bezos developed what he calls the regret minimization framework. In it, he asks one to visualize themselves at age 80 and ask if they would regret making (or not making) a decision. This simplifies decisions by making them about one metric: regret.

  7. Ignore “Black Swans”

    A black swan event is an entirely unpredictable event that comes out of nowhere. Doing so skews all data and beliefs, and people start to take the black swan into account as a new normal. But these are just outliers that should be ignored.

  8. Look for Equilibrium Points

    This mental model is about noticing trends in progress.

    When you first start something, you go from zero to one—that’s an infinite rate of progress. Then you go from one to two, two to three, and so on, and the rate of progress slows, and the returns start diminishing.

    Somewhere around there is an equilibrium point that truly represents what the average mean will be. Don’t make the mistake of not waiting for it.

  9. Wait for the Regression to the Mean

    This mental model is the final mental model about seeing the whole picture in terms of information.

    A change without reason for the change is not a change; it’s just a deviation. As such, it doesn’t represent what will continue to happen in the future.

    A regression to the mean is when things settle back down and resume what they were doing before—this is representative of reality.

  10. What Would Bayes Do (WWBD)?

    Bayes’ Theorem is something that does allow us to conclude the future: based on probabilities and taking into account events that have already occurred. All you need are the rough probabilities of three elements to plug into the Bayes’ formula, and you will come to a more accurate conclusion than so-called experts. This is basic probabilistic thinking.

  11. Do It Like Darwin

    Darwin was not a genius, but he did have one trait that set him apart from others: his undying devotion to truth.

    In doing so, he developed his golden rule (and our mental model) of giving equal weight and attention to arguments and opinions that opposed his own.

    Instead of growing defensive when presented with something that opposed him, he grew critical and sceptical toward himself. This radical open-mindedness puts aside confirmation bias and ego.

  12. Think With System 2

    System 1 focuses on speed and efficiency of thought, while System 2 focuses on accuracy and depth of thought. System 2 is smart, while System 1 is dumb.

    System 1 does more harm than good, but unfortunately, it is the one we default to because it is easier. Gain awareness of the difference between the two; acknowledge System 1, then jump immediately to System 2.

  13. Peer Review Your Perspectives

    Peer Review Your Perspectives. Many of the ways we fail at solving problems are related to our inability to look at other perspectives. We should be continually checking our perspectives through triangulation against those of others.

    Thinking and solving in a vacuum will never work because if you didn’t experience it firsthand, it wouldn’t make sense to you.
