Links this week:

  1. Psychological research sucks.

  2. Are humans getting cleverer?

  3. Why the $10,000 Apple Watch is a good thing, especially for people who can’t afford it.

  4. [O]ur findings suggest that correlations observed in affluent, developed countries between (i) wealth and health or (ii) parental income and children’s outcomes do not reflect a causal effect of wealth.

And no posts this week, although with Robert Frank joining Twitter, here are three book reviews from the vault:

  1. The Darwin Economy

  2. Passions Within Reason

  3. Luxury Fever.
