I am myself a retired applied scientist. And in the course of my extensive and wide ranging studies, I have found that many widely accepted "scientific" facts are simply accepted on faith that whoever first published such-and-such a study, did so correctly and honestly.
I personally am old enough to remember the great shake up when a stupid Japeneese student insisted that the human cell he was examining did not contain 24 pairs of chromosomes. Everyone knew there were 24 chromosomes in a human cell. This was well known to be thoroughly established scientific fact. But this one lone student just kept insisting that the human cell he was examining only had 23 pairs of chromosomes. The teacher finally examined that cell for himself, and was amazed to found that the student was right. Then they examined several other human cells and found the same. so the published a paper saying that they had discovered that some human cells only contained only 23 pairs of chromosomes, rather that the thoroughly established norm of 24 pairs.
This caused scientists all over the world to pull out the samples they already had in their cases, and actually count the pairs of chromosomes. It took less than two months for the entire world to know that it was incorrect that the human cell contained 24 pairs of chromosomes. It only contains 23 pairs, which is not thoroughly established and well known - until someone else also discovers that this new number is also wrong.
This took place in my University days, during the semiser I was studying cell physiology. It greatly shook my faith in "science" as a whole. For this was a simple matter of counting, that anyone could do. And everyone had both the samples and the required instruments already in their laboratories. But, since someone had written this number in a report, and someone put it in a textbook, everyone had simply accepted it as fact, and not even one scientist in the entire world had even bothered to check and see if it was correct.
As I continued my education, and afterward as I was employed in my field of expertese, I found many cases in which "scientists" had published erroneous information. Sometimes this was due to sloppy work. But all too often, it was due to willful deception. And as my research continued, I found two fields in which dissent was energetically quashed. In each of these fields, only the "majority" view was allowed. Dissent was not only scoffed at, but energetically condemned.
And these two fields were evolution and global warming. in both of these fields, anyone daring to even question the "consensus" view was energetically attacked. These very attacks prove that these ideas are not based on rational thought, but on chosen beliefs.
