Didn’t read the links but the numbers in your comment differ by 3x (7 billion vs 24 billion). Unless I’m misreading something?

The human mind is susceptible to priming. When I read the SciAm article earlier this week I was sure I read "200 Billion" since that is what I was expecting. But upon reading the conclusion that number made no sense and I swear the B magically became an M.

One is million vs billion.

Thanks. I was looking at the wrong number. The scale difference is in the "200" number.
