All science is anarchic.
Science follows rules, but not rulers. If there is a ruler controlling it, dictating what the results must be, it’s not science.
Those who want you to think of anarchy as chaos and “everyone doing what they feel like” are denying reality.
Actually, they are lying. It might not be their fault; they have probably been lied to and didn’t question what they were told. But it’s still a lie. And they are perpetuating the lie instead of questioning the assertion and putting it to the test.
