Peter Allen Mann · Author, The Perception Revolution and The Projection Fallacy
By environment, I mean the five systems: how you hire, run meetings, set priorities, review work and promote. Most run on unwritten rules that worked when you could see everyone. The people who can't read them do extra work to keep up, then go quiet or leave. This may include the person everyone called difficult who turned out to be right. Almost no one has priced that loss. Three numbers to start, all in your HRIS.

Peter Mann has spent 37 years in leadership, from a Navy warship to Fortune 100 divisions to two companies he founded, and retention stayed near 95% across them. He writes and speaks on why organizations lose the people whose judgment they most need, and what it costs them.

Why now
This generation is less willing to mask and stay quiet than earlier ones were. The generation behind them is growing up expecting support as standard. Most managers were never trained for this.
This has happened before. When women entered professional work, the informal networks that decided who got promoted didn't change on their own. Written criteria and structured processes did. The companies that made the rules explicit first got the talent.

The five explicit systems
When a machine fails, no one asks the operator to care more. They fix the process. People systems deserve the same treatment. Every workplace is built on the Projection Fallacy: systems that work best for minds like the ones that designed them. The cost shows up in who leaves first. These five follow the path every employee takes, from getting in to moving up.
A system is explicit when someone new can use it without asking.

Whether the concern that would have changed your decision ever reaches you. Scored at the narrowest point in the chain rather than the average, because a concern only has to fail once.
I work with a small number of leadership teams each year, often after an acquisition, when good people start going quiet or leaving unexpectedly, when new hires keep leaving in their first year, or when experienced people are retiring. We measure differential turnover and signal loss across the layers, change the systems behind them, and measure again.

Written for the person who designs the systems.
We all mistake our own experience for a universal one. The people who design systems do it at scale, and they can't see it from the inside. What that costs and how to build systems that produce fair outcomes without anyone having to believe in them.
If you run an organization and want one of them now, start with The Perception Revolution. The argument holds from either side.
