Or increasing taxes on the wealthy and using that to provide a better safety net.

Then we'll find out when it comes online! If the new theory is compatible with past observations, and correctly predicts something that GR gets wrong, that will be a huge finding! But the press has gone wild prematurely, as they often

It's not disqualified for not being simple, it's disqualified for not making testable predictions. Given two theories, neither of which make testable predictions, the simpler one (and the one that has been studied more thoroughly)

I believe the author's argument is: however simple or complicated dark matter and energy are, negative (inertial) mass just makes things even more complicated, without offering any new (testable) insights. The author herself points out

In this particular example, the "treatment" is implementation of ergonomic practices, and the "response" is worker productivity. If we divide a workplace into two segments, there almost certainly will be some difference

One of the desired outputs of an experiment analysis is an estimate of the size of the treatment effect, typically in the form of a confidence interval. Studies which only report statistical significance (and there are many of them) are of

In the context of experiment design, you do this because you want to know whether any apparent difference between the groups is plausibly an artifact of the random assignment of units to groups. You wouldn’t expect two groups to have identi

It just seems to me it is impossible to be surprised by a bounded random variable in this context. If the death sentence were carried out x days from now, where x is drawn from an exponential distribution, that would fulfill the surprising
