"As a rule, strong feelings about issues do not emerge from deep understanding." -Sloman and Fernbach Also, the Dunning-Kruger effect still applies to smart people. You don't stop when you are estimating your ability correctly; as you learn more, you gain more awareness of your ignorance and continue being conservative with your self-estimates.

Dude is using AI for a slop-post that complains that AI pundits are not persuasive enough and should take acting classes. Really, the one thing missing in 2026 is more and better AI propaganda!

>The people who know the most often sound the least certain As was beautifully demonstrated in this article.

It's revealing that the author thinks that a podcast is the ideal venue to reason through complex technical issues. The "like" phenomenon is less of a verbal fluency issue and more of a cultural one. You can listen to someone smart like Donald Knuth speak and he will definitely stammer and stutter a lot, but he doesn't use filler words. "Like" is more of a West Coast or California thing and I also find it annoying and distracting.

Not sure I agree with this. It's often true in SF, but that is largely an affectation, people imitating people like Peter Thiel etc. But not as true elsewhere

Just a little more effort and STEM people will discover the social sciences. Cute.
