In 1966, a University of Texas psychologist named Elliot Aronson ran an experiment to examine the role of imperfection on human connection.

Aronson recruited 48 college students and had them listen to an audio recording of a candidate supposedly auditioning to be on a "College Quiz Bowl" team (a popular TV format at the time).

The recordings were, in fact, staged. The candidate was just an actor working from a script. But the participants believed they were real and that they would be helping evaluate the candidate.

The participants were played one of four recordings:

1. Superior Candidate, No Blunder: Answers 92% of the difficult questions correctly. Sounds impressive. Modestly mentions an impressive resume.
2. Superior Candidate, Blunder: Similarly brilliant performance, but spills a coffee all over himself during the recording and exclaims, "Oh my goodness, I've spilled coffee all over my new suit!"
3. Average Candidate, No Blunder: Answers only 30% correctly, modestly mentions average resume.
4. Average Candidate, Blunder: Similarly mediocre performance, but spills coffee all over himself with similar exclamation.

They were then asked to rate the candidates on their overall likability for the quiz bowl team.

The findings were fascinating:

The superior candidate with the coffee blunder was rated the most likable of the four. The average candidate with the coffee blunder was rated the least likable.

The staged blunder had helped the competent person and hurt the mediocre one.

The researchers coined the term Pratfall Effect—theatrical slang for a sudden fall on the buttocks—to characterize a counterintuitive truth:

Competent people become more likable when they reveal small, harmless flaws.

They offered a ​simple explanation​:

"A superior person may be viewed as superhuman and, therefore, distant; a blunder tends to humanize him and, consequently, increases his attractiveness."

Now, that line was written in 1966, but it feels particularly relevant for the current cultural moment.

I assume I'm not alone in this experience, but my feed and inbox feels increasingly dominated by AI-generated content.

It's clean. Technically perfect.

It's also hollow. Like a sort-of grayscale version of perfection. It lacks depth, texture, and humanity.

The "AI slop" of the present moment isn't riddled with mistakes. It's actually the opposite. It's devoid of the mistakes that make it feel real.

For most of human history, polish was the signal of competence. Polished work was how anyone could indicate they were credible. But now, polish is free. Anyone can produce something that appears flawless in mere seconds, even if they don't have the earned competency behind it.

Accordingly, polish has, in some sense, lost its value as a signal.

The new signal is texture.

Texture is the mark of a human being who actually showed up, sat down, and did the work. The imperfection is your proof of humanity.

But it's important to remember something here from the study itself:

The Pratfall Effect didn't work for everyone. The mediocre candidate who spilled the coffee became the least likable of the entire group. The same blunder that humanized the competent candidate had hampered the average one.

The lesson: Competence first, pratfall later.

The company's successful "ugly ad" works because the product is genuinely valuable. The leader's admission of an error builds trust because most of their calls have been correct. The writer's typo creates connection because their work is so powerful.

Imagine a master carpenter creating a beautiful wooden table. He cuts the enormous block from a beautiful tree. Shapes it through meticulous effort. Sands away the knots. But he doesn't apply a finish. He doesn't smooth every edge. The natural grain gives the table character. Proof of life.

Your task ahead is no different.

Work hard to earn your competence. Build an irrefutable base of understanding and credibility. Then resist the temptation to smooth every edge.

I try to stick to three core principles:

1. Earn your competence.

You can't skip the work. Build competence. Create evidence. Through reps. Stacked days over a long period of time. There are no shortcuts here. Quiet progress creates loud results.

2. Don't sand all the texture away.

Once you've earned the competence, allow your humanity to shine through the cracks. Hit send on the unpolished post if it feels right. Turn your phone on and press record without doing five practice takes. Fire off the quick memo to the team at the end of the week. The texture is the way.

3. Never over-engineer a spill.

Fake, engineered coffee spills are easily spotted. People see through them much more often than you think. The whole point is that the humanity is real.

In a future flooded with faux perfection, the rarest, most beautiful thing you can be is human.

A ruthlessly competent, yet perfectly imperfect, you.

Embrace the Pratfall Effect. Every now and then, it's good to spill the coffee.
