I was going to do a one-year MSc at LSE called Social and Cultural Psychology but just saw a MSC at Queen Mary in London called Cultural Psychology and Psychiatry...the latter seems more on-target for me but is Queen Mary a respected institution in the U.K.? (I may be returning to the United States, but perhaps not, as of today [July 1, 2021] the U.K. automatically gives two-year visas for people completing a master's in the U.K., without a confirmed job offer).
(I had been thinking of Psychology, Culture and Evolution at Brunel but a British person told me I would be much better going to LSE).
