From Garry Trethewey
You report a finding that body odour produces less disgust when attributed to a member of the smeller's group, and Stephen Reicher's comment that because loyalties can affect a core biological response that shows how powerful and malleable group identities can be (27 February, p 20). I find it more interesting that a “core biological response” can be affected by psychosocial events. I wonder whether this is a basis for the placebo effect.
