Ah, there's the problem. The scientific method is great, but it doesn't apply itself. It's scientists that are the problem. Scientists are only human.

Let's do an experiment. Or better, let's do a Gedankenexperiment so we sound more like experts:

Look around your (virtual) workplace. See that well-spoken idiot who you know is wrong about everything, but who somehow gets the attention and the money to run whatever projects they want? That's the expert.

You are not the expert, even though you know more stuff, because nobody asks you. And when you insisted they were wrong, they got rid of you.

The same thing happens everywhere, in academia, science, government, medicine... everywhere. We are only human.

But not to worry! It's all right. Thanks to the scientific method science actually advances, even if it's one funeral at a time. Just be careful who you trust.
