  • Very important point, just one technical remark, because I see this a lot: You don’t necessarily want or need random samples in surveys. What you want is a probability sample, which means that you know the probability with which a person enters the sample. A random sample is a special type of probability sample, where each person has the same probability to enter the sample.

    The large sample used for this “survey” in the OP is a convenience sample, which is a non-probability sample, where the persons’ probabilities to enter the sample are simply unknown. And this is often not a useful basis for a survey, because it’s affected by all sorts of response biases that are difficult to adjust for in non-probability samples.



  • BARF is an acronym for biologically appropriate raw food, which is a kind of pet diet in which owners feed their pets raw food (some pet owners swear by it, I personally think it’s nonsense). This product looks like a pure supplement that is only meant to be added to raw food for extra nutrients.

    The left side is the position that definitions of intelligence are all arbitrary, and that psychologists just make up tests and call what it measures “intelligence.”

    The middle is the position that there is a real thing that can be called “intelligence,” which can be defined in different (meaningful) ways, and that intelligence tests are objective ways to measure it.

    The right side is the position that intelligence is probably still real and can probably still be defined in different (meaningful) ways, but that we can never directly measure intelligence and instead observe it indirectly through observable indicators like someone’s performance on an intelligence test. This means that any practical statement about intelligence, while probably real and definable, are contingent on the specific test used to measure it.
