    I disagree both with your characterization of my position as well as your assertion that it is “grotesque”.

    Skin color and sex can be used as indicators for hidden, hard to ascertain traits. It may be racist to assume that the indicator perfectly predicts those traits, or that skin color and sex predict hidden traits when they do not, or to assume that sex and race cause the traits to occur when they don’t. But it’s not racist or sexist to make assumptions based on race or sex if there is a real correlation.

    Sickle cell anemia is much more prevalent in blacks than in whites. It’s not racist to suggest that blacks should be tested at higher rates than other communities.

    Women experience more sexual assault than men do, and the vast majority of the perpetrators are men. It’s not sexist to assume that a woman who is assaulted was likely assaulted by a man.

    If we created some sort of viral genetically engineered cure for SCD tomorrow, race would stop being a predictor of that particular trait. If we found a way to bring male sexual assault down to the same rate as female sexual assault, continuing to assume the sex of a predator would be incorrect.

    And obviously, in legal or scientific contexts, we need hard evidence of the underlying traits themselves rather than assumptions based on sex or race.

    Assumptions of this sort can be racist or sexist when the person making them is motivated to come to a particular conclusion, but making assumptions is not inherently bigoted.

    In the original scenario, the assumption is that a group of people of various sexes and races have had different life experiences. There are relatively few downsides to this assumption. If you’re wrong, then you’ve mistakenly formed a group that is slightly less “diverse” than you hoped for. The upside is that you don’t need a full biography from everyone involved in the group in order to promote diversity of experience and opinions.

    To be clear, I find most manufactured diversity to be asinine, and I think that it can certainly be taken too far. That doesn’t mean that the actual assumption is incorrect.


  • Yes, of course many people are virtue signaling. But measuring true diversity of opinion and experience is difficult and time consuming, so people use race and sex as a proxy because it often does lead to diversity of opinion and experience.

    Red lights don’t reflect the true state of an intersection, but when the light is red it is a bad idea to drive. Similarly, a group of men and women of several races may have all been raised in the same neighborhood, but it’s unlikely.




  • The most basic way to measure movement is with an accelerometer. It’s a little component inside your phone that has a small weight with a known mass connected to springs. When the phone moves or rotates, the weight moves, and the tension on the springs changes. The tension is either constant (you rotated your phone and are now holding it in the new position) or temporary (you moved in a direction and stopped). There are other ways this can be done, but this is the most conceptually simple.

    Steps, length of step, distance moved, and heart rate can be estimated from analyzing the movement in various ways.

    For example, to detect a step, your phone might see movement slightly up and forward, then down, then a jarring impact. Heart rate can be estimated based on your entered weight in an app, your speed of movement, how long you’ve been moving, and averages for people of your weight moving in those ways. This is a very inaccurate way to measure your heart rate, however. A better way would be by a sensor located on your wrist, arm, or chest, which is what smart watches often do.

    Movement measured by an accelerometer can quickly become inaccurate, because small errors add up over time, so for movement over longer distances, phones generally use GPS (communication with a satellite positioning system) which is accurate to within about 5 meters.

    If GPS isn’t available, but the phone is connected to multiple cell phone towers, then it’s possible to triangulate the position of the phone given the tower locations. If we know the distance and direction to the towers, and the position of the towers, then we can find the location of the phone by basically adding an offset to one of the tower locations.

    There are other, more niche ways to measure positions without triangulation or GPS, but they’re generally used for autonomous robotics - laser positioning with reflectors, ultra-wide-band positioning with special sensors, or visual positioning with cameras surrounding the region in which the robot will be working.

    Let me know if you have any further questions.

    Difference in origin, sex, and culture lead to differences in experience and views. An all-male group trying to make decisions that affect women is going to do a worse job compared to a mixed sex group because they lack insight into issues facing women. Same for race.

    There are situations in which diversity of sex or race can lead to worse decision-making than a seemingly more homogeneous group that has diverse political and ideological views, as you say, but favoring the former isn’t a bad way to increase effectiveness. The alternative is likely an intrusive and difficult investigation to determine individual opinions and experience.
