The Law of Signal Conservation
• John Vandivier
This article describes a hypothetical model of signalling relevant to labor analysis.
There are many such models, but a possibly unique characteristic noted here is that transactions completed on the basis of a signal may involve a constant total signalling value even while signal sources vary.
Dr. Caplan is author of The Case Against Education which is forthcoming next January. Students of his GMU 895 course this Fall are privileged to review a chapter-by-chapter preview. In one lecture he casually mentioned the possibility of the existence of a law of signal conservation in response to a students question. This sort of melted my brain as it concisely puts a complex notion that I was attempting to include in my own work on alternative credentials.
Basically:
- Employers hire people they think will do a good job. They expect business productivity.
- Technical skill is a factor of business productivity.
- Social norms factor into business productivity.
- Weirdness exhibits and inverse bell curve with respect to productivity. Very weird people are generally very unproductive or very productive, while normal people generally have average productivity.
- Couple the above with risk aversion and you have an obvious explanation for employers preferring normal people.
- Another explanation for the preference of normal people is that it minimizes onboarding costs. People who are weird are weird in a variety of ways, but people are normal in a singular way. Standard onboarding targeted at normal behavior optimizes on both groups. Normal people are the larger Q group anyway, so that separately incentivizes onboarding to target that group.
- All of the above is a ceteris paribus analysis, but evidence-based credentials break this ceteris paribus assumption. With evidence-based credentials a candidate employee can credibly present to the employer as a member of a high-productivity group instead of a low-productivity group and their weirdness becomes an advantage. For example, having a PhD is weird but in the way that many employers will appreciate, and if you are a bit eccentric it's OK because your \"the kind of person who gets a PhD\" weird, like Sheldon Cooper maybe.
- Third parties directly engaging employers with evidence seems like an effective route to changing this norm. So, send your boss a copy of The Case Against Education and you will be doing the whole future labor force a favor.
