The Uses of Delusion summary

What if the path to self-understanding isn't just about accurate self-perception, but about clever self-deception? Psychologists Taylor and Brown argue that some of our most useful delusions come in the form of unrealistically positive self-views.

They highlight three primary self-flattering delusions: an overly positive view of ourselves, a belief that we have more control than we actually do and an unreasonably optimistic outlook on the future. These delusions spring from our innate biases. We tend to claim credit for our successes, while failures are conveniently blamed on external factors. We cherry-pick positive feedback and compare ourselves favorably with those less fortunate.

Imagine dribbling a basketball on the morning of a presidential election – a routine of Barack Obama during his campaigns. He transformed his habit of playing casual games with staff into an election day tradition, a superstition that took root after winning the 2008 Iowa caucus but losing the New Hampshire primary — the only differentiating factor being a game of basketball.

Despite the comforting rhythms of this ritual, it's clear there's no way a basketball game could sway the outcome of a nationwide election. This anecdote highlights an intriguing aspect of our behaviors and beliefs. We often engage in rituals and hold superstitions that, while they don't change the outcomes of external events, can affect skill-based activities, acting as soothing balm for our anxieties or encouraging preventative caution against reckless behavior.

Imagine being at dinner, gazing into the eyes of your beloved, and sharing your honest belief that you two aren't necessarily uniquely matched soulmates. That’s bound to cause a stir, perhaps even a heartache. The insistence on being destined for each other, despite contrary evidence, is quite typical in love stories. There's something comforting, almost essential, about the irrationality that comes with love – the unshakeable belief in soulmates, the promises of "till death do us part," despite the looming specter of divorce statistics.

This irrationality might not be entirely devoid of reason, though. Philosopher Berislav Marušić suggests that if there are practical reasons to maintain these vows, despite being aware of the odds, then they can be sincere. After all, who wouldn’t want their relationship to last?

In the annals of human discovery, there's a story of the self-taught scholar George Smith. In 1872, he made a significant breakthrough by translating a cuneiform tablet that relayed a narrative of a massive flood, strikingly similar to the Biblical tale of Noah. This tablet was a part of the Epic of Gilgamesh, one of humanity's earliest literary works. This intriguing story opens a doorway to understanding the age-old fascination and intricate theories surrounding our dreams.

Within the Epic of Gilgamesh, characters experience symbolic dreams that foretell future events. This reflects the ancient Middle Eastern and Greek cultures' belief in dreams as prophetic messengers. However, even in antiquity, not everyone agreed. The Roman philosopher Cicero, for instance, dismissed the notion of dreams predicting the future due to their often chaotic and nonsensical content.

Imagine being engrossed in a video game, conquering level after level, only to realize that you were not playing at all — the game was in demo mode. 

Now consider the teachers of nonverbal autistic students in the 1990s who used facilitated communication, a method where they guided their students' hands to type out messages. Convinced of the efficacy of this method, the teachers believed their students were the true authors of the typed messages. Yet, a study at the O.D. Heck Developmental Center revealed a startling reality: the teachers were unconsciously generating the messages themselves.
