IKR.

Pennebaker thinks so. He's a big proponent of "computational linguistics".

I recently read his book Secret Life of Pronouns.

I thought it'd be fun to replicate the book's claims. Like maybe analyze political speeches.

But Pennebaker's current rulesets apparently aren't available. And I didn't have the gumption to figure how to use the tools which are available.

Another book about truthiness is Everybody Lies by Seth Stephens-Davidowitz. https://www.amazon.com/Everybody-Lies-Internet-About-Really/...

There's got to be some overlap, right?

There are stats available from porn sites. E.g.:

Now we’re not saying that size matters, but 2018 was an impressively big year for Pornhub and its users. Visits to Pornhub totaled 33.5 billion over the course of 2018, an increase of 5 billion visits over 2017. That equates to a daily average of 92 million visitors and at the time of this writing, Pornhub’s daily visits now exceed 100 million.

2018 saw Pornhub’s average visit duration grow by 14 seconds to 10 minutes and 13 seconds.
