A lot of people wonder what the big deal is about experiments. Why do people care if, say, some particular dietary supplement has been supported by randomized experiments or not? If taking two St. John's wort pills a day helps me out, and my friends say it helps them, why should anyone care what some guy in a lab coat thinks? To answer that question, we need to start with explaining science in a slightly different way than most people are used to.

There is much talk about political correctness on college campus. This is including, but not limited to, discussion about Halloween costumes, trigger warnings, safe spaces, and issues involving feminism and race relations. I am not going to write here about my opinions regarding political correctness, or trigger warnings, or any of those issues. Instead I am going to focus on a very weird dynamic of this dialog: The fight over whether or not being politically correct is a restriction on free speech.

My PsycCRITIQUES review is about to release for James Tabery's book "Beyond Versus: The Struggle to Understand the Interaction of Nature and Nurture." Here are some highlights:

There have been many stories recently about the "overproduction" of Ph.D. students in science, and about the increasingly competitive job markets. This isn't going to be a comprehensive post about that, but rather a highlight of a short, but significant paper that might otherwise be under the radar. It is Academia's never-ending selection for productivity by Francois Brischoux and Frederic Angelier, in the journal Scientometrics. It's focus is on evolutionary biologists hired by the National Centre for Scientific Research France, between 2005 and 2014, 55 people in total from what I can tell. The NCSR has a stable and formulaic hiring process, which makes easy to compare hires across years. Despite the small sample, and the narrow focus, I suspect the same trends would be replicated in most scientific fields, at most academic institutions, in the U.S. Here is what I thought was the crucial paragraph :

Many struggle with discussions of null and alternative hypotheses. The logic behind phrasing research questions in that way can be a bit unintuitive. The logical involves what you can or cannot prove given an if-then statement, and I'll put a paragraph about that down at the bottom. In the meantime, here is a much easier way to understand what is going on:

So, after spending a long time in conversations about racism --- some time talking, but mostly listening --- I pressed those involved about on the "now what?" question. In response, I have been informed that it is my duty to go out and educate other white people. Seems odd, but there it is, and I'm gonna give it a try.

The terms Dependent and Independent can be a bit unintuitive, and many stats students struggle with them. The easier term should be "dependent", and that term is easiest to understand in an experimental context. The dependent variable is what you measure at the end of an experiment.
