> best practices immunizes

I see this all the time when digging down into why. "It's ok to shut off my brain and just do X, regardless of whether it's situationally even useful." Just as bad as "Policy". It's ok to not think and find a good solution, as long as the bad solution looks "normal" enough.

Best practices are inherently decades old. It takes a long time for a good idea to spread and get people used to it. It's very likely there are better ways to solve the issue around, if you stop to think and read.
