Survival of intellectual curiosity

The whole brain changes allowing scientific objectivity explained in http://gettingsciencegoingagain.blogspot.se/2015/01/non-status-science-is-possible.html also solves the mystery of intellectual curiosity. If intellectual curiosity was a specialized "psychological mechanism" selected by environmental change, it would devolve again during the stable periods between climate changes and never reach a high level. But if the absence of cognition/emotion distinction mean that intelligence itself creates intellectual curiosity, the mystery is solved. By the way, this also solves all sorts of mysteries of behaviors that are evolutionarily disadvantageous: intelligence itself just creates a lot of behaviors without specialized "mechanisms".
