In addition to New Scientist, Wired, and MIT's Technology Review, some books Ellen, Anne, and I are reading this summer include:
The Hidden Brain
Predictably Irrational (scroll down)
Naked Statistics (Prepping Ellen for her stats class this fall; reviewing my stats from grad school)
All highly recommended, along with the granddaddy of human behavior / decision-making's book: Daniel Kahneman's Thinking Fast and Slow, discussed here in context by our friends at Less Wrong.
