USA – -( Profiling is needlessly a misunderstood concept. What's called profiling is part of the optimal stock of human behavior and something we all do.

Let's begin by describing behavior that might come under the heading of profiling.

Prior to making decisions, people seek to gain information. To obtain information is costly, requiring the expenditure of time and/or money. Therefore, people seek to find ways to economize on information costs. Let's try simple examples.

You are a manager of a furniture moving company and seek to hire 10 people to load and unload furniture onto and off trucks. Twenty people show up for the job, and they all appear to be equal except by sex. Ten are men, and 10 are women. Whom would you hire? You might give them all tests to determine how much weight they could carry under various conditions, such as inclines and declines, and the speed at which they could carry. To conduct such tests might be costly. Such costs could be avoided through profiling — that is, using an easily observable physical attribute, such as a person's sex, as a proxy for unobserved attributes, such as endurance and strength.

Though sex is not a perfect predictor of strength and endurance, it's pretty reliable.

Imagine that you're a chief of police. There has been a rash of auto break-ins by which electronic equipment has been stolen. You're trying to capture the culprits. Would you have your officers stake out and investigate residents of senior citizen homes? What about spending resources investigating men and women 50 years of age or older? I'm guessing there would be greater success capturing the culprits by focusing police resources on younger people — and particularly young men. The reason is that breaking in to autos is mostly a young man's game.

Should charges be brought against you because, as police chief, you used the physical attributes of age and sex as a crime tool? Would it be fair for people to accuse you of playing favorites by not using investigative resources on seniors and middle-aged adults of either sex even though there is a non-zero chance that they are among the culprits?

Physicians routinely screen women for breast cancer and do not routinely screen men. The American Cancer Society says that the lifetime risk of men getting breast cancer is about 0.1 percent. Should doctors and medical insurance companies be prosecuted for the discriminatory practice of prescribing routine breast cancer screening for women but not for men?

Some racial and ethnic groups have higher incidence and mortality from various diseases than the national average. The rates of death from cardiovascular diseases are about 30 percent higher among black adults than among white adults. Cervical cancer rates are five times greater among Vietnamese women in the U.S. than among white women. Pima Indians of Arizona have the world's highest known diabetes rates. Prostate cancer is nearly twice as common among black men as it is among white men. Using a cheap-to-observe attribute, such as race, as a proxy for a costly-to-observe attribute, such as the probability of some disease, can assist medical providers in the delivery of more effective medical services.

For example, just knowing that a patient is a black man causes a physician to be alert to the prospect of prostate cancer. The unintelligent might call this racial profiling, but it's really prostate cancer profiling.

In the real world, there are many attributes correlated with race and sex. Jews are 3 percent of the U.S. population but 35 percent of our Nobel Prize winners. Blacks are 13 percent of our population but about 74 percent of professional basketball players and about 69 percent of professional football players. Male geniuses outnumber female geniuses 7-to-1. Women have wider peripheral vision than men. Men have better distance vision than women.

The bottom line is that people differ significantly by race and sex. Just knowing the race or sex of an individual may on occasion allow us to guess about something not readily observed.

    1. I was in Las Wages waiting to get on an airplane.
      The women ahead of me was 95 years old in
      A wheelchair and the TSA selected her to be searched.
      I assume they strip searched her because they took
      Her in a room. This poor lady was wearing a diaper.’
      I’m sure she was humiliated. Profiling would be
      A better choice.

    2. Strange, Rather than groping old ladies, and young boys the Israelis PROFILE passengers at the airport and seem to have a greater success at stopping terrorists than the TSA. The Israelis also do NOT xray and SNIFF people on the way to their flights.

      1. Do you know that Israel is also much more gun friendly than the US? Israel is much more logical about things like gun ownership and combating terrorism by necessitate and having dealt with the Israeli Air Force in my younger days can understand why. Yeah, I think we would be better off but the left would be going bat-s–t crazy, not that that would be a bad thing! 🙂

    3. If profiling didn’t work, it wouldn’t be used. Therefore, it is a necessary tool in the old box. If the left would stop trying to PC everything, Americans would be safer, less stressed and generally better off.

    4. Another well-thought-out and logical article. Thank you Dr, Williams for your contributions on suck important topics. I read your articles all the time.

    5. Which parts of “specific and articulable evidence for suspicion” and “kndividualized suspicion” don’t you understand?

        1. Jim:
          The point I understand is that if a person is dark or dusky complected, speaks loudly to another of the same description in Arabic, has four wives in tow all wearing head coverings, and is seen kneeling on a small piece of carpet while waving his butt in the air and simultaneously banging his head on the floor, …………….
          Then, any attention paid to him or his entourage is grounds for a legal proceeding and someone is guilty of PROFILING.
