Scientific Reasoning Explains Increases in IQ

The bombshell is that the Flynn Effect is almost certainly environmental. Natural selection has a speed limit measured in generations, but the Flynn Effect is measurable on the scale of decades and years. Flynn was also able to rule out increases in nutrition, overall health, and outbreeding (marrying outside one’s local community) as explanations for his eponymous effect.241 Whatever propels the Flynn Effect, then, is likely to be in people’s cognitive environments, not in their genes, d...

If something is followed by punishment, it was wrong; if it is not, it was right. The light-fingered 5-year-old mentioned before was at this stage. A second stage considers reward as an important indication that something is right. The stress in these early stages is on works, not faith—rightness or wrongness is identified in terms of what a person actually d...

 The Stages of Moral Development

Kohlberg outlined a progressive process for moral development: 1. Avoiding punishment. Moral reasoning starts out at a fairly primitive level, focused mostly on avoiding punishment. Kohlberg calls this stage pre-conventional moral reasoning. 2. Considering consequences. As a child’s mind develops, she begins to consider the social consequences of her behaviors and starts to modify them accordingly. Kohlberg terms this conventional moral reasoning. 3. Acting on principle. Eventually, the ...
