If a scientific paper makes a conclusion, that doesn't mean its a correct, valid, or properly supported conclusion.

You instead look at the claim and the data and the experiment methodology. It often says something far far less generalizable or significant than the conclusion section of the paper.

The thing about experimental science is that you should not make much conclusions from one study or one paper. Those should wait till consensus is reached, till there are many independent studies confirming the same thing under various conditions.
