They may not have asked that question, but that seems to be the question people were answering. Isn't it somewhat obvious that we almost never answer the literal question?
If I consider the situation where the parent left their 2 year old alone to go meet a lover vs going to work to put food on the table, I'll judge the former situation more harshly. To explain myself, I'd say both situations put the child at the same risk, but the first situation is not a responsible reason to assume that risk.
In short, when you present these scenarios, you're not asking me, "mathematically, which situation is more dangerous for the child?". You're implicitly asking me, "is this parent making a responsible decision?".
It seems likely to me that the respondents deviated from the question strictly asked using at least in part that reasoning.
I'm not saying the reason itself changes the risk. I'm saying the reason gives me insight into the kind of parent a person is and the likelihood of their being higher risks in the child's environment. Or to use your analogy, there's probably a lot more 'land-mines' in the house of a parent who leaves to play pokemon than in the house of a parent who left their child alone due to an accident or unforeseen circumstances.
If you can't see that than you are blinded by your own sense of rationality.
Isn't it more likely that the drug-addicted parents are more likely to leave drug related paraphernalia around. I'm talking about mostly-empty baggies of cocaine, methamphetamine, weed, whatever. Needles, bongs, half empty bottles of booze.
Isn't the drug-addicted parent more likely to not be aware or not care or not notice all sorts of other safety related issues.
Probably the working-parent shouldn't leave a child under a certain age unattended. But it seems perfectly reasonable that people should judge the drug-addict house as more dangerous.
I don't claim to have full knowledge of every situation, but as someone who spent the better part of a decade injecting meth on a very regular basis I feel my opinion ought to carry some authority.
Do you still feel the child is in more danger if left unattended by the drug-addict parent leaving to buy drugs versus the working parent leaving to work? How about the drug-addict parent leaving to work versus the working parent leaving to buy drugs?
But that statistic is based on general population. My contention is that our moral judgement can be used to heighten perceived risk to a child, even though it might blow it well out of proportion. So just because the average child is at a perceived risk of being injured at x% when left alone, I don't think it's wrong to say a child of parent I judge to be amoral or willfully negligent is most likely at an increased risk of being injured.
For those circumstances where that is the case then ok.
Now that the people really answered a different question that they were actually asked is another thing. Not uncommon with humans in psychological studies.
This research is saying we shouldn't change our assessment of the risks to a child in a situation based on our moral assessment of their parents. I'm saying the fact that the parents are drug addicts or willfully negligent is likely indicative that the child IS at higher risk that the statistical average.
Not sure how I can make this any clearer in any of my responses.
The risk to the child for a specific situation does not change based on the reason why a parent put the child in a situation, the same way that the probability of getting hit by a landmine doesn't change based on whether you're walking across a minefield to cheat on your spouse or to save a baby.
The researchers wasn't asking "how good of a parent do you think they are", they were asking "how risky do you think this behaviour is", and it is irrational to be changing your estimation of the risk in a situation based on the reasons for being put in that situation (but what else is new when it comes to human psychology).
