Our current Surgeon General is another diversity hire. It’s apparent any time he opens his mouth. 🤦‍♀️

I have a biostats master's degree, which was extremely rigorous and difficult, basically doing calculus 8 hours a day for the first year, but I would argue that lack of math isn't truly the core problem. Academics often miss very simple things. In the first large project I worked on (as a graduate student), which was data from a computer-guided telephone survey of new breastfeeding mothers, the computer program contained an erroneous "skip" that caused the majority of women to skip past many of the vital questions to the end of the survey. Another student had worked on these data for 9 months (!!) and never noticed the immense amount of missing data.

Another project I worked on, there was a massive outlier in the data which completely changed the regression results depending on whether it was included or excluded. No one had simply plotted the data. It was a swarm of data points showing no trend but with one huge outlier driving the entirety of the slope estimate. There are statistics to identify outliers / high-leverage data points, but really, you just needed the simplest plot to see there was an issue.

Another project I worked on regarding mercury levels in dentists failed to control for mercury spills in the office, which was available data, but had been ignored. A mercury spill within the previous 6 months was a significant predictor of mercury levels and altered several models and conclusions once accounted for. No one had apparently read the entire survey and thought "Hey.... might this be a confounding variable?" Except me.

Speaking of confounding, ask just about anyone in academia what negative confounding is. They won't know. It's when there are two opposite trends which tend to co-occur. For instance, for one of my clients studying women in Kenya and their usage of professional midwives, having more money was a positive for hiring professional help, but having more children was a negative (because they were old hands at it by then). Well, women with more children tended to have more money, so the positive (money) and the negative (old hands at it by now) canceled each other out. Neither seemed related to the decision to hire a midwife, but that was incorrect. Both had to be taken into account *simultaneously* to see the true effects. Which is also true of healthy / wealthy / educated status and harms caused by vaccination; they are opposite effects on mortality, but they co-occur, so must be addressed simultaneously. It's negative confounding. Few in academia seems to grok this concept.

The stupid runs deep. But math isn't usually the problem in my opinion -- PhD statisticians adore mathematical models and want to outdo each other with the latest, most complex clustered-data time series multi-level sampling blah blah blah. Meanwhile nobody does effing scatter plots.

It's an inability to think with genuine curiosity, in my opinion, more often than it is a lack of rigorous math. I'm convinced academia now is deliberately churning out useful idiots because a system this complex and this corrupt needs a great, great many of them in order to run.
