PainSci notes on Humphrey 2012:
Humphrey and Skoyles proposes an evolutionary explanation for the placebo paradox: even though it might be possible in theory, in practice our brains dare not routinely invoke powerful recovery mechanisms because they have costs that often outweigh the benefits. Here’s some excellent extra reading from Todd Hargrove, who did a nice job interpreting and explaining this idea. The additional perspective is most welcome.
