In about a month, UCL will be hosting an event in memory of Vittorio Girotto (see HERE). I’m very proud to be involved, looking forward to meeting some good friends and presenting joint work with Vittorio as well (this paper and this talk will be the starting point, although I’m not entirely happy anymore with several details and I’ve been revising them meanwhile). Vittorio was an outstanding researcher and a great friend. If I ever got to do anything decent in connection with the psychology of reasoning, he’s one of those I should thank first. (Memories of many other friends – some in Italian – have been collected HERE.)
