Is a pretty sure sign of confusion.
Here, in reference to the “Science is Real” portion of those signs, is Richard Feynman:
Learn from science that you must doubt the experts. As a matter of fact, I can also define science another way: Science is the belief in the ignorance of experts.
When someone says science teaches such and such, he is using the word incorrectly. Science doesn’t teach it; experience teaches it. If they say to you science has shown such and such, you might ask, “How does science show it — how did the scientists find out how, what, where?” Not science has shown, but this experiment, this effect, has shown. And you have as much right as anyone else, upon hearing about the experiments (but we must listen to all the evidence), to judge whether a reusable conclusion has been arrived at.
