Science is finding where your errors are, so you know precisely how wrong you are.
In some fields we have 5 zeros before the % of error, in some fields we have almost 40% of error possibility.
Or sometimes 2 theories that "disagree" actually applies to different cases or different approaches, sometimes they have both high error, but close possibility of error, so it is worthy to invest in both.

The scientific revolution was done when we stopped trying to tell why we are correct and start calculating how wrong we might be.
