Income relative to IQ, by occupation

++Addition++Steve Sailer adds some flavor, pulling from his personal experience in a marketing research firm.

---

With occupational average IQ estimates constructed from median income and, separately, from wordsum scores, the question of which occupations garner earnings higher than the IQ of their practitioners would predict, and which occupations bring in less than IQ would predict, naturally arises. The following table ranks occupations by the income premium they enjoy relative to the average IQ (via wordsum scores) of their practitioners. That is, it is a crude measure of how overpaid (positive) or underpaid (negative) they are relative to their converted IQ averages. The value displayed is simply the difference between the median income-derived IQ estimates and the wordsum-derived IQ estimates used in the preceding two posts. Occupations included have a minimal sample size of ten:

 Occupation Diff 1. Physician 44.1 2. Dentist 29.8 3. Commercial airline pilot 19.3 4. Pharmacist 17.4 5. Attorney 13.4 6. Farmer 10.4 7. Economist 10.3 8. Bricklayer 9.7 9. Telephone installer and repairer 9.6 10. Sheet metal worker 9.0 11. Civil engineer 8.2 12. Butcher 8.2 13. Electrical engineer 7.3 14. Forklift operator 7.0 15. Electrician 6.5 16. Aircraft mechanic 6.2 17. Mechanical engineer 6.1 18. Computer programmer 6.0 19. Truck driver 5.7 20. Roofer 5.3 21. Tool-and-die maker 4.7 22. Firefighter 4.6 23. Architect 4.5 24. Physical therapist 4.0 25. Automobile mechanic 3.4 26. Mail carrier 3.0 27. Dental hygienist 2.9 28. Janitor 2.6 29. Construction worker 2.5 30. Plumber 2.3 31. Registered nurse 2.3 32. Welder 2.2 33. Accountant 1.4 34. Computer systems analyst 1.3 35. Engineering technician 0.8 36. Stockbroker 0.8 37. Sales representative 0.2 38. Carpet and tile installer 0.0 39. Bus driver (0.1) 40. Licensed practical nurse (0.4) 41. Furniture upholsterer (0.9) 42. Painter (1.3) 43. Chemist (1.4) 44. Police officer (1.6) 45. Psychologist (2.2) 46. Stenographer (4.1) 47. Taxi driver (4.4) 48. Insurance agent (4.5) 49. Security guard (4.7) 50. Telephone operator (5.5) 51. Barber (5.9) 52. Cashier (6.0) 53. Teacher (6.4) 54. Dressmaker (6.8) 55. Child care worker (7.2) 56. Bank teller (7.5) 57. Photographer (7.9) 58. Social worker (8.0) 59. Real estate agent (8.6) 60. Artist (fine art) (8.6) 61. Waiter (8.7) 62. Maid (8.9) 63. Actor (9.4) 64. Receptionist (10.0) 65. Secretary (10.3) 66. Retail salesman (10.3) 67. Clergyman (10.6) 68. Librarian (11.6) 69. Author (12.1)

Advanced medical fields populate the top of the list, an outcome that is not surprising given the amount of time and effort that must be expended by those entering these fields before they are able to begin practicing professionally. The situation is similar for pilots and attorneys. Other occupations near the top of the list, such as butcher, roofer, and sheet metal worker get there due to the physical demands and generally undesirable working conditions they entail.

At the other end are those who make their livings by way of what they write, something bloggers are certainly able to appreciate!

Some occupations in which compensation might initially appear to be low relative to the cognitive abilities of those working in them are influenced by other factors. In the case of teachers, this includes working around 60 fewer days than people in jobs with conventional schedules do. Additionally, teachers enjoy extremely high job security.

If any true average IQ is going to be inflated by measuring it using a vocabulary test like the wordsum, it is going to be for librarians. Still, I suspect librarians tend to be introverted types for which gregariousness is not usually a personality trait that describes them, and their earnings suffer for it.

Finally, who knew economists were overpaid?!

Physicians and dentists have a huge negative aspect to their job:
They frequently have to deal with people who are of less than average intelligence and general functionality. Most other high-iq professions never have to deal with people of average or lower intelligence. In a lot of specialties, they also need strong physical attributes (mostly manual dexterity) to be good at their craft besides raw brainpower.

The take home message for readers of this blog is: be a part-time pharmacist and use your leisure to write.

Marty Nemko, who picked out pharmacy as winner, is a good source of hard-nosed career advice:

But due to recently lengthened training Pharmacy drops off his top-rated list:

Librarians are next to last. When I worked in marketing research, I used to try to recruit librarians on the grounds that the marketing research business wasn't all that different from being a librarian (assuming you have decent quant skills to go with your verbal skills), but it paid better.

Then, I became an author (last on list). Hmmhmmmhmmm ...

I love this thought-provoking post.

I’m working as an English teacher in South Korea, and I think I am in the positive: My salary matches the average teacher’s salary in Korea, but I work almost 10 hours less than the average and have my apartment and airfare paid for. http://www.worldsalaries.org/education.shtml

I’ve only got a B.A. and it’s not in English or teaching of any kind.

As a side note, becoming a full-time teacher in Korea is insanely difficult for native-born Koreans. Korean teachers, I believe, are underpaid as they must be extremely sharp to get a full-time job. As for the foreign English teachers, they’re IQs probably match those of average college grads, give or take, but the perks they get are pretty positive.

Simon,

Professor/academic is not included among the 200 occupations in the Career Cast data. I'm not sure why that is--it's not for lack of the occupation's size, as far less common jobs like roustabout show up.

This is fascinating. As a lawyer, I find it especially interesting that attorneys are relatively low in the "overpaid" segment. It perhaps suggests that the attorney cartel may not be as distorting as is often thought.

Income figure MUST be adjusted for the costs (both direct expenses and opportunity cost) of obtaining necessary education and/or license. Otherwise results is pretty inaccurate.
For example, time and cost of medical school and residence training etc will move physician number downward very significantly. Similar for pharmacists (and authors - while not required by law in this case ...)

On my father's side, we have some cousins who are infrequently spoken of, and a bit of an embarrassment to the family. But a lot of them are linemen and do make good coin despite not being even big state school material. I'm guessing that falls under telephone installer and repairer?

Librarians introverted? I suggest you get yourself some librarian friends and get drunk under the table by them. But maybe we are just used to drowning our sorrows over low pay and negative stereotypes ;-)

Being a public librarian should be one of the most extrovert things going. You are in the public eye all the time, talking to people all the time (lots of questions) and promoting your service with it.

I'm the branch manager in my town - everyone knows who I am. I get stopped in supermarkets. Kids shout "Hello Ian" in the street. It' great and I love it.

And I never say shhhhh.

Shame over one in nine libraries in the UK are under threat of closure at the moment. Perhaps that a reason why we're not high on the list...
