Corrupted thinking and cancerous co-option

The conversation this week starts off on corruption. There are allegations of political or corporate malfeasance in the news regularly throughout the world. But can science bring anything to the investigators? We look at some efforts to bring empirical rigour to the fight. But corruption of sorts is also a big thing in our online lives.
