You’re fulfilling the Idiocracy prophecy. Those who think about their life choices are less likely to breed than those who are more reckless and have children with less hesitation. The similar survival rate of children of the two groups means the more-reckless genes & culture will out-propagate the less-reckless genes & culture. I’m pretty sure less-reckless is what we need more of, but without some extreme and questionable measures, I don’t see how it’s possible to sway the force of nature.
