An engineer will say a bridge will fail, or a foundation they designed 20 years ago will give way under 4x the load it was designed for, but the politicians and businessmen at the top will overrule them, people may die, and the only person blamed will be the engineer, despite the paper they wrote and published years before saying to tear the 60 year old bridge with spalding concrete and rusted girders down.

You can lead a horse to water, but you can't make them drink it. The same goes for accepting reality, hence why many choose to live in an alternative reality.
