【英文】
Many people feel uneasy when scientists change their minds. One year a food is said to be healthy, and later experts seem to say the opposite. Such reversals make it tempting to think that science cannot be trusted, and that its conclusions are merely opinions that change with fashion.

This impression, however, comes from a misunderstanding of what science is. Science is not a fixed collection of facts but a method for testing ideas against evidence. A scientist proposes an explanation, checks it with observations or experiments, and revises it when new evidence does not fit. Because the process is designed to find its own mistakes, change is a sign that the method is working, not failing.

A useful comparison is a map. An early map of a coast may be rough, and later maps show more details as explorers collect more information. The new maps do not prove that the old one was worthless; they show that our knowledge has become more accurate. In the same way, most scientific revisions refine earlier ideas rather than destroy them. A theory that has survived many tests usually remains valid within the range where it was tested, even if a wider theory later explains more.

Of course, science is carried out by humans, and humans make errors, follow trends, and are sometimes influenced by money or pride. Poorly designed studies do appear. But the scientific community has ways to correct these problems: other researchers repeat experiments, criticize weak methods, and question surprising results. Trust should therefore be placed not in any single study but in the accumulated body of work that has been checked many times.

For ordinary readers, the lesson is to ask how strong the evidence is, rather than to expect certainty. Accepting that knowledge is provisional does not mean giving up on truth. It means holding our beliefs with the right degree of confidence, and remaining ready to update them.
