Second, we must place the research discussion into context. The recent replication crisis has shown that modern science, and especially social science, is deeply corrupted. The findings of many — if not the majority of! — highly cited studies that have influenced policy and culture cannot be replicated. In other words, they are completely unreliable. This is another reason to be skeptical and prefer randomized controlled trials, which include two of the large-scale studies I cited above showing negative effects.
It is important to assess the value of caregivers because they are what truly make society function, and often their work is under-appreciated. They prepare the next generation for school, work, and decision-making. The way in which a child is nurtured at a young age and through adolescence has both psychological and developmental effects that effect their future. Not only does the child depend on caregiving, but schools and employers depend on the childcare. The government also benefits because these children turn into productive members of society. Eventually, they will be the ones running the country.
