## Takeaways

1. Researchers had no assigned projects or quarterly deadlines.
2. Annual one-page reports fed a technically informed peer review.
3. Managers compared multi-year contributions before setting raises.

## About this segment

Brian Kernighan describes a hands-off research culture with annual peer reviews. Technical managers weighed contributions over several years rather than demanding quick results.

## Transcript

Transcribed by machine (Whisper) from the episode’s audio, so a word may be off here and there.

[16:38](https://realalpha.app/v/sMllOlxVgD0/?t=998) What's stopping a researcher from coming in at three, leaving at five, not having any output? There was no immediate stop to that period. There were no deadlines. There were no projects. There were no objectives, goals, whatever, set by other people. The mechanism for deciding whether you were doing anything was that once a year, you had to write down on one side of one piece of paper what you had done.

[17:07](https://realalpha.app/v/sMllOlxVgD0/?t=1027) And we called it the I am great report. And it just summarized what you've done. And then the first and second level of management would sit in a room with the I am great reports from their people. So this would be maybe 30 at the bottom, half a dozen, one like that little tree. And they would discuss the merit of the contributions of the work that was being done by the people. And they would come up with some sort of ordering which says, you're better than I am or vice versa.

[17:40](https://realalpha.app/v/sMllOlxVgD0/?t=1060) How would we compare to our peers? And that would give them a sort of roughly a rank ordering or at least equivalence classes of people. And if somebody hadn't done anything for a couple of years, that would be noticed. But if somebody had gone off on something and it didn't pay off very well or it was still in progress, but it was OK or whatever, that was OK. That's the long view that I mentioned before.

[18:03](https://realalpha.app/v/sMllOlxVgD0/?t=1083) It's not like, what have you done for us the last week or even quarter? What maybe have you done over the last two, three years? And it was being assessed by people who were not driven by quarterly numbers. They were the same people as we were, except that they had moved into management, but they were still technically active and they were very technically knowledgeable. And then the process was repeated a couple of levels up until they had an effect or rank over the name of everybody.

[18:30](https://realalpha.app/v/sMllOlxVgD0/?t=1110) So that was kind of the called abstract merit. You know, you know, I'm better than you are. And then there was the concrete merit phase where we've got this much money. How much do you get? How much do I get? So there were bonuses or tied to. it wasn't bonuses or anything like that it was simply there's a pot of money this is the raise pool and it will be over all x percent and so you will get x minus epsilon i'll get x plus epsilon or vice versa oh and that was once a year and that was the whole story but it was it was very deliberative the management was collegial if you and i were managers and we had our people It wasn't like my people are better than your people.

[19:13](https://realalpha.app/v/sMllOlxVgD0/?t=1153) It's rather, hey, you forgot to mention that Susie did this really great thing. Don't forget Susie kind of thing. So it was quite collegial and you would be evaluated by people who understood the work and whose goals and aspirations and so on were the same as yours, you know, do good stuff. It sounds like you mentioned that their technical is like a big part of this whole system. Why is that important?

[19:38](https://realalpha.app/v/sMllOlxVgD0/?t=1178) if somebody is doing something in a technical area they have created a new program they've proved a new theorem they developed a new process whatever if you are not technical enough to understand what they're talking about it's hard for you to tell the bullshit from the actual useful content right so i could not you personally but i could blow smoke Look. pretty well for people who were, I don't know, who shall I insult? MBAs. Okay. Something like that. That's obviously a slander. But it's easier to blow smoke at somebody who is not sort of knowledgeable in your own field. But the people that you were, who were evaluating your work were exceptionally knowledgeable in the whole field. And so they had a pretty good eye for what was good stuff and what wasn't yet good stuff
