The best thing you can do is wonder what currently accepted data is wrong. That’s actually the best mindset that a scientist can have.
It’s because of that constantly questioning mindset that we are where we are today.
All of our advancements and growth in science (and a lot of things really) have come from the idea that “what if this isn’t right or isn’t good enough?”.
If you aren’t a scientist you sure have the scientific mindset
You sure are right that it’s not easy to challenge, but it is something that must be done. And even if it is something that is disproven, it still provides a benefit as it rules itself out as a false possibility. Failures in experiments are really just as important as success, as it still provides a net gain of knowledge.
