Probably just more objective and impartial people vs. better. It does not take a particularly good scientist to look at studies - the sample size, source, methodology, etc. and current data, and determine if something is logical/probable or not. It is what it is, good or bad, but I really feel some people, even scientists, inject their beliefs and biases, both for and against Trump. As more data comes in, there should be more of a consensus, but it seems that’s not the case.
