People Hacks: The 7 Most Useful Truths About the Mind You Missed from Psychology Class
The longer you live, the more you realize that the difference between success and magnificent failure lies in how well you understand people. If you’re like many, that fact makes you regret not having studied psychology. I hate to be the one to tell you, but holding both a BSc. and an MSc. in psychology – yep. You missed a lot.

And yes, I am analyzing you as you read this.
But there’s good news, too. You don’t have to attend lectures on multivariate statistics, neuroscience, or early childhood development to learn about what makes people tick. There are dozens of excellent books on human psychology that will get you an education without a semester’s worth of classes.
The following 7 truths are what I consider the most valuable things you can learn from the past few decades’ best books on brains. They’ll offer you some insight into why you make decisions the way you do, what that potential client is thinking, and why you should worry about your slightly sinister boss.
1. You’re irrational (but that’s okay – if you know how to handle it).
Most of us assume we are rational decision makers, but in the last 10-15 years many books have challenged this assumption. One of the most notable among them is Nobel Prize winner Daniel Kahneman’s Thinking, Fast and Slow. Kahneman shows that a vast majority of our decisions are made in seconds and based on emotions and intuition – a fact that leads us into traps and makes us vulnerable to manipulation and poor choices.

Of course, your irrationality isn’t always a handicap. Malcolm Gladwell explains in his now-famous book, Blink, that intuitive decision-making can help us do what we’d never be able to manage without it. Take the gaze heuristic for example. It’s a simple shortcut in decision-making that takes us outside rational thinking to act faster than our minds can process. It’s the gaze heuristic that allows athletes to perceive a baseball flying through the air and move to catch it without doing any serious mental calculations. It’s knowing without knowing – irrationality at its best.

2. You underestimate the role of chaos and luck.
Nassim Nicholas Taleb wrote The Black Swan and Fooled by Randomness to address that we humans a) tend to underestimate just how much chaos defines our lives, and b) use hindsight logic to explain whatever happened, even if it was based on chance. So, if the universe runs on chaos, doesn’t that make a panoply of everyday acts of trust incredibly risky? The answer is yes. Allowing a broker to put your savings in the stock market, for example, is quite a risk. After all, take a long look and you realize that what they do is mostly gambling.

Just as irrationality isn’t always a bad thing, randomness can work in your favor, too. In The Wisdom of Crowds, James Surowiecki suggests that sometimes the best thing we can do is trust to collective judgment. Studies like those of social psychologist Gerd Gigerenzer show that if you want to invest smart, you might be better off asking random people about which brands they know and putting together an investment portfolio based on their answers. Gigerenzer’s studies indicate that such a seemingly haphazard approach gives you a better chance of good returns than would handing over your savings to that sleazy Wolf of Wall Street guy.

3. You’re needlessly obsessed with talent.
That we take talent to be the main predictor of success might have to do with our tendency to seek cause and effect. However, many studies have shown that talent isn’t essential when it comes to excelling in life and work. Gladwell’s Outliers, Talent is Overrated by Geoff Colvin, or Cal Newport’s So Good They Can’t Ignore You show that while talent is helpful, it’s never the be-all, end-all.

We’ve already established that luck has a lot to do with our perceived successes – why else would the month in which they were born be a good predictor of ice-hockey players’ eventual success? In Outliers and Mastery, the writers take it a step farther to explain that success is mostly about gaining experience, practicing, and achieving mastery of a skill. What does all this mean? Simply, that (a lack of) talent is no longer an excuse not to try to succeed at what you want to do.

4. Negativity is in your nature, but you can change that.
In his How the Mind Works, Stephen Pinker explains that, from an evolutionary perspective, it makes sense for humans to be negative creatures. Pricklier emotions like fear and anger rescued us from predators and enemies. Meanwhile, positive feelings such as gratitude and pride were the evolutionary deadbeats – nice to have lying around, but not doing a whole lot to aid in survival.

On the other hand, researchers are now realizing that people tend to live longer, more fulfilled lives when they’re happy – even dodging disease due to it. Positive emotions might not have been critical for our caveman ancestors, but for the modern day office worker, happiness is key. In her book Positivity, Barbara Frederickson shares the recipe for a happy life: 3 times as many positive emotions as negative ones. According to positive psychologist Martin Seligman, author of the book Learned Optimism, even the most negative person can get happier (or at least closer) with simple exercises like writing gratitude letters or meditation.

5. You actually love working (but might not know it yet).
Flow is a many splendored thing. In his classic book on the concept, Mihaly Csikszentmihalyi describes flow as the state in which we lose track of time and enjoy being in the moment. Because it strikes the perfect balance of pleasure and progress, flow is the final frontier in working well.

According to Daniel Pink’s Drive, humans are built with this neat feature called intrinsic motivation – a zeal to do something due to a feeling of internal satisfaction. Intrinsic motivation is natural to humans: we are predisposed to perform, to work, and to tackle problems. We can see it in our primate ancestors, who actually enjoy solving puzzles without any external reward or other reasons to do it. So why do so many of us perceive work as drudgery, not play? Neil Fiore’s The Now Habit explains that we’re trained to lose our joy in work at school and by our parents. But with the right mindset, there’s no reason you can’t revive your inner child and start enjoying what you do again.

6. Focusing on the Now is the key to both productivity and happiness.
So, why is flow so hard to harness? It means abandoning everything but the “now” and focusing on the task at hand, something that’s quite difficult for most people. It’s worth it to try to get there, though. The closer you can come to complete in-flow focus, the more you will get done, and the happier you’ll be.
7. Charisma holds a lot of power over you – and your boss might actually be a psychopath.
Even the earliest self-help books such as How to Win Friends and Influence People note that the impression you make on others is one of the most powerful tools in your kit – and in that of others. Others, like psychopaths. As it turns out, it’s charisma, not handcuffs and diabolical plots, that will often bring you into a psychopath’s field of influence. These people tend to have high amounts of charisma and know how to use it. According to books such as Snakes in Suits and The Wisdom of Psychopaths, psychopaths often end up in positions of power due exactly to this magnetism. Your concern regarding your ex boss-zilla and his hunting trips might not be so farfetched.

So, what is it about charisma we find so very tantalizing? In The Charisma Myth, Olivia Fox Cabane tells us that what actually wins over others is giving off the impression that you’re powerful (wealthy, strong, or influential) and will use your power to help them. But that’s just one type of charisma – leading with warmth is also an option. The simplest, soundest advice on upping your charisma goes back to Carnegie’s classic and is just one word long: smile.

Now, you’re filled in on all the key psychology concepts you missed while you were busy studying something else. I hope you learned something about the mind you can use in your everyday life – even if it is only adopting a gorilla as your new pre-presentation spirit animal.
