In present-day Japan, many people believe that conclusions drawn from past information will not change in the future.

For example, ideas like "if you lack athletic ability, you cannot become an athlete" or "as you age, your abilities decline."

These thoughts support the mindset of "I have failed before, so I will fail again" or "it's pointless to try."

The facts we have now are merely conclusions based on past information, and there is always a possibility that they will be overturned in the future.

In the late 19th century, physics was thought to be complete, but the discovery of quantum mechanics disproved that notion.

The truth that "humans must die" also has the potential to be overturned with the discovery of iPS cells.

If we can think, "today's failures may be tomorrow's successes," people can act more actively.

Therefore, it is better not to overestimate what is "correct" now and to treat it as a provisional hypothesis.
