A Brief Note on Using Scientific Evidence

A common technique among statists is to cite scientific evidence that phenomenon X is important and that phenomenon X might be affected by human activities and conclude that phenomenon X must be regulated (and regulated their way).

One example, there is clear evidence that climate change is important and some evidence it might be affected by human activities. Is the way it is important the same as the way it might be affected by human activities? It is important from the point of view of avoiding an Ice Age and human activities might make the climate warmer. Those don't seem to go together.

Another example, there is some evidence that genes affect IQ and some evidence that genes vary between human populations. Are they the same genes? There is a lack of evidence on that score.
