Data: TED Talks ranked by persuasiveness, moral content, laughs, narcissism, and more

Owen Temple (@owentemple) was curious: What makes some TED Talks so persuasive?

To get his answer, he applied Natural Language Processing and Machine Learning to metadata and transcripts of all posted TED Talks and published Words of Persuasion: Text Predictors of Persuasive TED Talks.

I found that the change in negative and positive emotion words across the talk and the speaker’s use of key social pronouns like ‘I’ and ‘we’ made a big impact on persuasive ratings [by viewers].

Which talks were the most self-focused or narcissistic?

Frequent use of the words ‘I’, ‘me’, and ‘my’ is associated with narcissism, depression, and reduced persuasiveness ratings. Here are the most self-focused TED Talks (click for full ranking).

Have persuasive topics changed over time?

Owen revealed that “Money words and Moral words were predictive of increased persuasion ratings,” and “the average percentage of Moral words has increased over the past decade while the average percentage of Money words has remained flat.”
