I don't know if this is true or not, but I beg you, don't post comments like this. It's a question, and you could've spent the extra minute of research to _actually find out_ and post that.

This way we are left with negative value: We don't know any better, and instead are mentally burdened with speculation, that we have to actively work to not muddle up with what we know later on.

You can do better!
