Change the world

To change the status quo, you must prove that it is wrong. It is not enough to challenge the established principles to prove themselves correct. The problem is that proofs outside our established ideas do not tend to register. We have to question our assumptions before they can be proved wrong.

When you're trying to change people's minds, remember this: the scientific minds of the time watched Galileo drop unequal weights from the Tower of Pisa. They hit the ground at the same time, contrary to popular belief of the time. These scientists walked away maintaining their old assumptions. They saw absolute proof and did not believe.

PS - A challenged assumption proved right is much stronger than before.
PPS - A challenged assumption rejected is less likely to be tolerated in others.
