Most claimed research findings are false, and that can be shown rather than merely suspected.
It can be proven that most claimed research findings are false. Here I will examine the key factors that influence this problem

The more analytical freedom a field allows in designs, definitions and outcomes, the less likely its published findings are to be true.
The greater the flexibility in designs, definitions, outcomes, and analytical modes in a scientific field, the less likely the research findings are to be true.

A hotter field with more teams racing on the same question produces less reliable findings, not more.
The hotter a scientific field (with more scientific teams involved), the less likely the research findings are to be true.

What is a korrent?
A korrent is a belief a person has stated in their own words: one sentence stating the claim, backed by a quote and a source, kept at korrents.com.
Under a name here, the quoted block is what they actually said. The korrent beneath it is the claim those words support, in korrents' wording — tap it to see the record, its source, and who else holds it.
Nobody here wrote their own korrents. They are compiled from public statements, and a person can change their mind, which is recorded too.
