"It provides only extremely weak support for that hypothesis. A reasonable prior expectation is that it is unlikely for a randomly selected group of young children to share a mistrust of adults that would carry on throughout their lives." I think you misunderstand gizmo686's point. My reading (of gizmo686's post as well as the study) is that this is not about a question of merely the individual child's responses but also about their environment, which at the age of 3 is going to be primarily controlled by their parents. It's not just a matter of whether a child who grows up mistrusting the world is at a disadvantage. It's more that a child who grows up in a world that is untrustworthy is at a disadvantage. Let me be blunt, we are talking about shitty parents. Or, to tone it down one notch, less capable parents. On the one hand you have parents who can provide for their children, who are attentive to their needs, etc. Those parents will tend to raise children better, and will tend to raise children who grow up to be more successful. On the other hand you have parents who let their children down often, are unable to provide for them as well, make promises that go unfulfilled, etc. Those parents will tend to raise children less well, and will tend to raise children who grow up and have more problems in life, problems finding jobs, problems with law enforcement, problems with relationships, etc. In broad strokes this is essentially what the second experiment is trying to show that the first experiment is testing. By intentionally priming children to either be trusting or untrusting of their immediate environment and of adults they show that they can control the outcome of the marshmallow experiment. And that in turn leads to the argument that perhaps it is a similar degree of priming (through the ongoing experiences with their family) and the underlying level of trust for adults that is being tested in the first experiment. It's not an ironclad experiment but it's an interesting hypothesis, certainly, and at the very least it unravels some of the overly simplistic interpretations of the first marshmallow experiment. |
I would add that it's possible that the two marshmallow experiments have very little to do with each other besides using children and marshmallows to perform. Further study is needed to make further conclusions.
For example, we might be tempted to try to combine the results and say something like "kids who trust and respect authority do better in life as adults." But this is not what the study/studies measured, and while this study may inspire interesting hypotheses for future work, that work needs to be performed before we can make conclusions.
