Be a Naysmith

‘In early Terran history, during the dominance of the Sumaturan dynasts, naysmiths were employed by the ruling classes. Their job was to disagree. To question everything. To consider any argument or policy and find fault with it, or articulate the counter position. They were highly valued.’

— Horus rising, Dan Abnett

Sometimes fiction contains wisdom. Even if it is Warhammer 40K fantasy.

Companies should have more "naysmiths" and less people who agree for the sake of safety and career development.
