You don’t have to have experience with something to give advice about it

This is how the world of academia and many consulting services exist.

If we all needed to go through it personally to be able to give advice about it, development would be extremely slow.

Humans are smart enough to sit down and learn about a topic and then package and present those ideas to the people who need it.

Of course, when giving advice, it’s better to have a mixture of both real experience and lessons learned from research, but drawing from both individually can provide more concentrated value from either side.
