Here are some favorites. Cognitive Daily has a discussion of the persistence of racism even among the well-intentioned.
Neuroscientifically Challenged writes on The Neuroscience of Distributive Justice.
In My Mascot Only Gave Me Sex Appeal Podblack Cat takes on superstition, luck, and natural disasters, with a focus on toys, Tibet and the earthquake in China.
And the Neurocritic himself has a very nice You’re My Favorite Person… on beauty, relations, dopamine, and immune activity.
