Not trusting anyone based on feelings or emotions rather than through knowledge, experience and unbiased information is also a very dangerous thing.

It can lead people down a path towards cults, religions, and authoritarian leaders and movements that have all the “answers” for you.

There is no greater power for an individual to have than a broad range of knowledge and information from reliable vetted, openly available, openly shared and universally accepted sources. If your guru had secret knowledge that no one knows about, chances are that information is either no good or it is unacceptable for a reason.

And also remember “keep an open mind, but not so open that your brain falls out”
