> Do newborn babies have an intuitive understanding of gravity?

I really had no idea about this one, but how it's studied is very interesting.

That’s interesting because much of the thesis was rooted in behavioral economics. The faculty that turned it down initially were in the economics department

Do you know which book?

It's one of the three of his books I own, I'm afraid I can't easily narrow it down further. (I own all three as audiobooks, and I recall Simon Jones reading it, but it turns out he read all three.)

• Predictably Irrational

• The (Honest) Truth About Dishonesty

• The Upside of Irrationality

Tangentially related I wish there were a way to “search” within audio books. Once you’ve finished the book its almost impossible to figure out where a specific chapter or passage is if you’d like to go back.

The semantic data format people have had a point all along. Just because digital audiobooks are inspired by books on cassette is no reason the data format can't support all sorts of metadata. We could have a format for written and read aloud works that highlights every word in the text on a screen as it's read when used in the proper player software, with user notations, bookmarks, indexes, an completely searchable by full text.

Kindle supports this with Whispersync. I don't know how the file format works.

They'd rather charge you separately for a DRM-locked ebook version.
