The first step to publishing null results is to learn about equivalence testing, and design studies that statistically support the conclusion that there is no meaningful effect. https://t.co/pwFRiNn8M8. If you are a statistics teacher, include this into 2nd year courses.
Scientists overwhelmingly recognize the value of sharing null results, but rarely publish them in the research literature https://t.co/1hHDfFFoh3

Misuse of p-values is a prevalent issue in scientific research. P-values are often misunderstood and misapplied, leading to incorrect conclusions. A p-value measures the probability of obtaining results at least as extreme as the observed ones, assuming that the null hypothesis

We misunderstand elite performance. It isn't a puzzle of tiny tweaks. It's a game of fixing glaring holes. Decades coaching top athletes taught me: 99% of success is mastering the fundamentals. Stop chasing marginal gains; master the basics.
