You're comparing apples and oranges. What we know about our ball earth and heliocentrism are as close to solved science as it gets. I don't know much about climate change theory, but for the purposes of this conversation let's just say it's less settled than heliocentrism (we know and can predict patterns of the Earth's movement around the sun into the far future with great accuracy, but there is no such accuracy with prediction of climate change).

But you compare those to diversity training efficacy, which has no empirical evidence, and the controlled studies examining effects have conflicting results. This is just not an honest comparison at all. I dismissed your study because it literally doesn't tell me anything about the real world, not because I hand-waive anything that I don't agree with.

Would you change any of your own life habits based on how 100 college kids subjectively reported on their feelings? It's ridiculous to compare the amount of information that kind of study tells us to the astounding accuracy of how our heliocentric model of the solar system can and has predicted where and when solar eclipses will happen down to the minute.
