The idea of skepticism is on a verge of extinction in today's conventional system. Most of us are inclined to accept the objective truths without a sense of doubt (considering you're not a flat- earther). The point is that it isn't necessary to accept a fact without prior skepticism.
For instance, in mathematics we are often told in conventional schools that to add two rational numbers you need to figure out the lowest common multiple, the rule of sign's is when you multiply a minus and a minus you get a plus, they tell you about the representation of numbers in the decimal system and nothing about how that came into existence or the fact that the sun rises from the east and sets in the west everyday. We're told these things and then its the end of the story, no questioning.
The truth however is that you take the lcm to add two rationals for the sake of convenience with regards to measurements, otherwise if we would have just added the numerator and denominator of such numbers we would have absurd quantities, In any case that doesn't disprove or prove the way we add rationals, but the point is that we're are never informed. The other one about the sign rule, it turns out the reason behind that is to satisfy the distributive property of arithmetic. And it also turns out that the sun rises from the east and sets in the west only on two days of the year and on other occasions it just rises from one direction and sets in some other direction.
The point is that the conventional system is flawed and that doesn't help generate interest. When a statement, however true it might be, when presented without its background and how it came into existence, makes that statement go in vain. That's where skepticism comes into play, the ability to look behind an objective truth makes that truth even more acceptable. And that ability is what we need to chase, rather than just accepting things without prior investigation.
