Remember those radio commercials that included the line “People judge you by the language that you use”?

Well, an on-line tutoring firm, Preply, has taken that idea and applied it to making a determination of the “intelligence” of CEOs based on transcripts of public appearances available on YouTube.

The firm analyzed from 60 to 180 minutes of dialog and assessed the execs based on:

• Vocabulary breadth: The extent of word diversity
• Vocabulary sophistication: The complexity of words used
• Textual readability: The complexity of sentence structures and ideas
• Critical thinking: The quality of argument construction, deconstruction, and analysis
• Contextual relevance: The speaker’s ability to interconnect the dialogue with broader contexts or other fields

That led to the scoring based on a 100-point scale.

And the auto CEOs included in the rankings don’t score in the top 10, not even Elon Musk.

Ranking first is Demis Hassabis, CEO of AI firm DeepMind, with a score of 87.33. Presumably he is exceedingly articulate (and/or has great speechwriters) because Stephen Schwarzman of investment firm Blackstone is in second place with a score of 74.33, a precipitous drop.

As for the people in auto, Musk is in 16^th position with 64.33, behind Brian Chesky of Airbnb with 65.00 and ahead of Whitney Herd of Bumble, at 64.00. (Strange correlation with Airbnb and Bumble. . . .)

Mary Barra of GM isn’t far behind, in 20^th position with 63.00.

There is one more U.S. auto exec on the list of the top 100: Ford CEO Jim Farley at 98, with a score of 32.00.

That just seems mean.
