Ideologues are everywhere.

If it isn’t presented as a theory that might be proven wrong, or an idea that might not work, that’s when my alarm starts going off.

Another signal: trying stuff we already tried that didn’t work, usually with an unconvincing reason why it’s different this time.

In many contexts "already tried" does not apply under "this and this conditions" though.

You can try the same thing under different contexts and it will probably yield different results (at least in any context that is organizational / social)
