Selection bias…

• emteycz 4y ago
  So non-uber drivers don't want to be uber drivers and uber drivers want to be uber drivers? Or what? There was practically nothing else in common between each driver other than their desire to continue working with Uber as they do now. Where's the bias? 500+ rides (probably significantly more bcs I have two accounts) are large enough sample.

    The selection consists solely of current Uber drivers, excluding all drivers who chose to stop and take an alternative job. As well, drivers in the act of driving are less likely to admit that they do not want to be doing what they are currently doing, due to cognitive dissonance. Additionally, there likely exists a framing bias along with a false dichotomy, if they were asked whether they’d rather Uber or take a “normal job”. There are of course plenty of alternatives that are not “normal jobs” (whatever that is exactly). Anyways, anecdotally, I’ve had drivers who were not happy with Uber and continued only out of lack of current options or plain inertia.

  Survivorship bias, which is a subtype of selection bias, is what I was contemplating along those lines. https://en.m.wikipedia.org/wiki/Survivorship_bias https://en.m.wikipedia.org/wiki/Survivorship_bias Now if I could somehow know whether I have any biases I should be aware of, I’d greatly appreciate that information, Steve.

    Yup, this selection bias is also survivorship bias.
