    When you mature as a human being, whatever age that may be, you develop kindness through a willingness to understand and empathize with perspectives that conflict with your own. That doesn’t necessarily mean you have to accept it for yourself. For many people, clothing is not simply a means of pragmatic function. It’s also a source of self-expression, joy, and beauty. Now for me, $600 for a pair of sneakers is exorbitant and ridiculous no matter who designed it. But it’s not a product for me. And if someone with the means feels great buying and wearing them, I don’t see the harm. I don’t usually pay more than I have to for footwear, but I would pay a premium for certain kitchen tools I use all the time if I like the design, enjoy looking at it, and feel good using it. What I do sympathize with and would like to see reduced in harm is the consumerist culture that pressures people with less means into feeling like they have to have such things for fulfillment.



  • I was talking about how widespread BMI is used in health sciences, I.e. everything from basic physiology to clinical trials to program evaluation to epidemiology. This is different from medical practice, e.g. family doctor taking your BMI. Whether it makes for good science or not, it’s use makes it part of science and replacing outdated tools is part of the broader scientific process–that doesn’t make the tools “not science”.

    You’re asking about “accuracy” which is a good question, as well as “precision”. However in health sciences we usually evaluate such measures more thoroughly with similar concepts of validity (construct and discriminant) and reliability; you’ll also see sensitivity in the literature but it’s a kind of discriminant validity.

    So if you do your own search using “BMI” and these terms on PubMed or even Google Scholar, you will find a range or scientific evidence. Most will say BMI is not good but not terrible, even good in some specific contexts. You will also find lots of evidence of how BMI is associated with other health indicators and health outcomes. I’m not going to spend an hour collating this for you. “Review” is also a useful search term. You seem smart enough to do it if you really want it. In any case, the argument is moot because we agree BMI should be replaced.

    Edit: okay I was curious comparing BMI to WtHR and actually found a couple cherry-picked examples that might be interesting for you

  • I completely agree, we need to move on from BMI. But it’s a bit silly to say it’s BMI isn’t science when it’s been used for the entirety of modern health sciences. People would be shocked by how many crude, yet useful enough measures that health sciences use even today. And it’s notoriously slow/stubborn in adopting the best tools for many methods. Still, humanity has continued to make scientific progress with them.


  • That argument is likely a distortion of the medical argument which goes something like, “People who are overweight by the medical definition of BMI between 25 and 30 are not necessarily unhealthy. There are some circumstances such as being an athlete or genetics that are associated with denser body compositions. BMI is a crude tool that is useful for some things but should not be used on its own to indicate health status.”
