"Why not a proof/Sign/indication" - challenge and various responses to it in Quran.

[Aoi Magi]

That's not how peer review works. If scientist x makes an observation, it doesn't count as evidence if scientist y can't make the same observation. If scientist x obtains data from an experiment, that data - even if it's accurate - must be discounted if scientist y can't reproduce the experiment.

Scientists are just as biased as everyone else; but the scientific method is deliberatly designed to reduce or even remove those biases as much as is possible.

Blind assumption that everybody in the jury is doing the experiment "honestly"; is a blind slack cutting in the sake of the jury's authenticity.
I know what peer review mean; and that is not what I'm presenting here.

I'm presenting that humans tend to repeat the same actions of others; so the trials and experiments get repeated despite having different judges; and that produces identical opinions; or in other words: biased opinions.

Scientific experiments are totally different than philosophical ones, or historical ones.
You can smell bias when the peers chosen are usually from the same field of study. I just think so many people are subject to bias in their opinion and conclusions.

If one doesn't do the experiment "honestly" they are going to get caught out by others performing that experiment. That's how many fraudsters have been outed so far... by the scientist community itself.

And what do you mean with "historical ones"? Archaeological finds are indeed testable and are peer reviewed, just like any other branch of science.
