There has been selection pressure in the other direction. Being<br>
conservative about accepting new ideas is adaptive because many new<br>
ideas are worse than the old way of doing things, which has worked for<br>
generations.<br>
<br>
Past ice ages may have altered the balance. If the stresses they<br>
cause on populations are enough that the old ways no longer work, then<br>
people who cling too tightly to the old ways will die out, and less<br>
conservative people will be selected for.<br></blockquote><div><br></div><div>### The timespans are incommensurate, climate change has no bearing on the evolution of psychological traits, where pressures operating over much shorter timespans are predominant. The reasons why primitive societies in the EEA are conservative is because they are poor and many experiments are expensive enough to cause death in days or weeks, not because of exposure of ancestral populations to changing climate conditions over thousands of years.</div>

We have constructed a world where everything changes much faster.<br>
Being conservative in such an environment is less adaptive.<br>
Conservative pressures not to develop new power sources may result in<br>
a tragic die off. It may not be just the conservatives dying, though.<br></blockquote><div><br></div><div>### Who are the "conservatives" doing the pressuring here? Do you mean the people who want to strangle nuclear power plant development?</div>
