Really, few know. When it comes to the kinds of internal biases that make you likely to reject a certain type of babysitter, if you’re self-aware enough to know which ones you have and honest enough to be willing to admit them then you’re definitely in the very small minority. Most just have no idea.  And most who do know would not out and say them in a public forum.

No, most people are going to say that they’d only reject people based on generally accepted supposedly “neutral” criteria such as how safe the person is, how well they know the person, how honest the person is, or how much the person likes children. People will say it depends on the individual and that they’d take each incident on a case by case basis.

The one exception to this is the borderline case of indoctrination which many consider an acceptable general non-biased criteria for rejection whereas others think it’s fine to choose someone who would “indoctrinate” their kids. I think the difference depends on whether the person thinks their children CAN be indoctrinated by a babysitter.IE if your world view is that children need to be sheltered by alternative ideas then you’re likely to reject anyone with strong opinions who might influence your children. But if your view is that kids needs exposure to lots of different views you’re likely to only have a problem if a single babysitter were spending so much time with the kids, that their strong world view became the primary influence on the kid and they weren’t also exposed to alternative perspectives.

Indoctrination aside though, it’s way less interesting who people SAY they will allow to babysit their kids than who people actually DO allow to babysit their kids.

For example if you were to study the data and see that lower middle class heterosexual males almost never selever a homosexual male to babysit their kids, then that might be an indication of a bias conscious or unconscious amongst lower middle class heterosexual males against homosexual males. On the other hands if those same lower middle class heterosexual males choose homosexual males to babysit their kids an inordinately large amount of the time then that might be an indicator of a bias in the other direction. Perhaps heterosexual males see homosexual males as safer by and large than heterosexual males. Or perhaps heterosexual males are concerned about the appearance of bias and OVER-correct by choosing homosexual males more frequently.

Similar analysis can be done for all those categories.  And although I have no hard data I’d be willing to bet large amounts of money that there’s generally a similar community bias across most categories to some degree or another. People tend to want someone who they perceive as similar to them and the people they know and interact with on a regular basis to babysit their kids because those are the people that they generally associate with being “safe”. There are almost certainly additional biases that exceed and transcend that, but I’d bet that that’s the biggest bias that drives babysitting choices. I’m also pretty sure economic standing and political ideology also could be added to the list of biases that drive unconscious tests to see if a potential babysitter is sufficiently “safe”.
