He refers to Stephen Pinker as a 'psycholophaster'.<p>Having never heard it before, I looked it up. It appears that Taleb made it up.<p>The acronym PHAST stands for 'participatory hygeine and sanitation transformation'.<p>'The approach is a participatory learning methodology that seeks to help communities improve hygiene behaviours, reduce diarrhoeal disease and encourage effective community management of water and sanitation services'<p>So my best guess is that Pinker is someone who applies this sort of methodology to mental hygiene. I'm not sure the term will catch on quite the way 'Black Swan' did.
