Just to tip you off that there is an opportunity (if you're VERY quick) to hear 2 fantastic speakers curated by the Herdmeister Mark Earls. At the RSA tonight. Alex Bentley and Mike O'Brien are respectively an archaeologist and a social scientist who are applying evolutionary biology to behavioural change. They held us rapt at the MRS conference yesterday. If you are interested in herd thinking and social change then you should try to get a ticket.
