Why two and not three or one?
- skh 8y agoIf two independent labs can reproduce the result it is extremely unlikely to be the result of false positives. The difference between having two versus three independent verifications is minuscule. A standard has to be set and 2 is a good enough standard.

If the underlying study is scientifically sound then a single repeat is good, two repeats is better. 20 repeats is even better. Good luck getting 1 or 2, unless the study is an important work that introduces a useful new technique or is the basis for additional studies. Also good luck knowing whether 2 labs failed for every 1 published. Science is hard. Reporting needs to be improved and there should be grants available to fund repeat studies.

But situation changes for three, because you cannot know who revealed secret, so it's much easier to crack. Imagine, I will report today that I'm able to determine temperature of the physical vacuum (e.g. using double slit experiment), and then able to drop it, i.e. cool vacuum below absolute zero. Will you trust me? Of course, not. Then when you will trust me?
