Statistics
Were they wrong? Not entirely. Were they right? Partly.
Repetitive action (habit, perseverance, or whatever you may want to call it) in the wrong direction is still wrong. You just get better at being wrong.

Management
In our previous example, where statistics rule, there is no such thing as a bad manager. The success of the team was purely as a result of following strict processes. The manager was the stick who made sure that you were following the rules, and the financial bonus was the carrot.
The Emotional, the Hands-off, the Micro-Manager and the Entrepreneurial Manager
I have worked for all of the above, and I have learned so much from each of them.
The Emotional Manager
No Process, and results are a matter of chance
They say you should do one thing today, and then the opposite tomorrow. They have no clear strategy or process, and therefore no clear parameters for measuring performance or attributing praise or blame. They would be better off in a team of one.
The Hands-off Manager
Some Process, and the results are in your hands
They will let you succeed (or fail) on your own terms. They may or may not have benchmarks for measuring success / failure, and they may or may not have procedures in place. Working for someone like this is the next best thing to being self-employed. Go forth and experiment.
The Micro-Manager
I am the process, and the results are all my doing
It's my way or the highway. This person does not welcome feedback on the system (or lack of). Just do as they say (and not necessarily as they do), and even then, they will take the credit for everything.
The Entrepreneurial Manager
Process is evolutionary, results are understood, and the team is central to that
This is really the holy grail of management styles. Usually this person runs their own business and they are very much a part of the business. If you have hopes of working for yourself one day, this is the best person to learn from and to collaborate with. You can question this person and be assured that they will have sound and balanced business reasons behind what they do and why they do it. You can trust them to put process, quality and results on an equal footing and you can recommend them with confidence to your network. They harness the collective expertise of their team and place a great deal of value on it.
