! You're Arvind? I had no idea. Gosh, the past few days have been interesting for me - first Piotr Wozniak tells me he's incrementally reading 8 articles mentioning or by me, then Danny Hillis replies to a comment of mine over at the Technium, and now here's Arvind Narayanan.

I'd say that any post that's good enough to get voted up to the main page is worth tens of thousands of dollars to mankind. Easily.

On one hand, I agree - if a main page post improves one high-value person's time, that alone is probably a few tens of thousands' worth. The other part of me is cynically remarking that Wozniak and psychologists in general have been advocating spaced repetition for the last >2 decades / centuries (respectively), the research is unassailable, and yet... So what's the marginal return on another literature survey?

A few comments:

• You mention creatine on your blog. Creatine only works in specific demographics; I don't know whether they include you.
• You mention dual n-back; the results seem to keep getting weaker since Jaeggi 2008, and Jaeggi 2011 seems extremely weak. I used to be extremely enthusiastic, but as the studies keep coming in... At this point, I'm not sure how much time is worth putting into DNB for just the WM benefits. Probably not much past D5B though.
