Hogwash. You have just convinced yourself you aren't making decisions that's you actually are making.
This was said in regards to beliefs and whether or not we choose to believe.
I have been trained in mathematics and physics. In math, we *prove* every statement we make (other than what we label as conjectures). In other words, from the basic assumptions and rules of logic, we proceed to demonstrate every fact of mathematics.
So, when someone offers a proof of a result, we look it over and determine whether they used correct logic or not. if they did, then the result is proved and we believe it. If not, the result is not proved and we do not (yet) believe it.
Whether or not logic was correctly applied is similar in many ways to determining whether a move in chess is correct or not. There are certain rules and we determine if those rules were followed or not. it is not a matter of choice.
So, no, in math we do NOT choose to believe or not. The statement is either proved or not. We believe when it has been proved.
Physics is a bit more complicated because it deals with the 'real world'. That ultimately means that all beliefs are held provisionally. But that doesn't mean they are all equal. We observe a phenomenon. We then try to form a hypothesis about that phenomenon. That hypothesis needs to be testable (if it turns out to be false, there should be some observation that will show it is false) and be able to make predictions about future observations.
We then go out and actually do the observations. If what we see contradicts the hypothesis, we either change it or abandon it. if it agrees with the hypothesis, we have more confidence in that hypothesis. But we try again to prove that hypothesis *wrong* by a new observation.
After many cycles from many different people, we have a great amount of confidence that the hypothesis works. But there is 8always* the possibility that a new observation will go the other way and we will have to modify or abandon that hypothesis.
And yet, even if a new observation shows the hypothesis wrong, it can *still* be good enough to allow us to design computers or send a probe to Mars. it may have passed 10,000 tests and failed one. But it was good for those 10,000 tests and any *new* hypothesis has to ALSO match those 10,000 tests 8and* match the new observation.
And that means that any modifications are going to be very minor in those things where the old hypothesis worked. Computers won't suddenly stop working.
But, the point is that it is NOT a matter of choice whether to believe or not. Either the available evidence matches the hypothesis and it has passed enough tests to provisionally adopt it as our working hypothesis (i.e, we believe it) or the hypothesis is failed or incomplete and we either disbelieve it (when it failed) or withhold judgement (when it hasn't passed enough tests yet).
