What I have discovered after working in medicine for pretty long is that many biologists and MDs think p-values are a measure of effect sizes. Even a reviewer from Nature thought that, which is incredibly disturbing.

p-values were created to facilitate rigorous inference with minimal computation, which was the norm during the first half of the 20th century. For those who work on a frequentist framework, inference should be done using a likelihood-based approach plus model selection, e.g. AIC. It's makes it much harder to lie.
