Preschool: Much More Than You Wanted To Know by Scott Alexander – ‘Good randomized controlled trials have shown that preschools do not improve test scores in a lasting way. Sometimes test scores go up a little bit, but these effects disappear after a year or two of regular schooling. However, early RCTs of intensive “wrap-around” preschools like the Perry Preschool Program and the Abecedarians found that graduates of those programs went on to have markedly better adult outcomes, including higher school graduation rates, more college attendance, less crime, and better jobs. But these studies were done in the 60s, before people invented being responsible, and had kind of haphazard randomization and followup. They were also small sample sizes, and from programs that were more intense than any of the scaled-up versions that replaced them. Modern scaled-up preschools like Head Start would love to be able to claim their mantle and boast similar results. But the only good RCT of Head Start, the HSIS study, is still in its first few years. It’s confirmed that Head Start test score gains fade out. But it hasn’t been long enough to study whether there are later effects on life outcomes. We can expect those results in ten years or so. For now, all we have is speculation based on a few quasi-experiments.’

Rationalist:

Preference Changing by Brian Lui – A five step process for changing your preferences: ‘To change a preference we must first confront its reality. To change our preferences, we need to deeply understand them. Next, we need to increase the contrast between instances of the desired behavior and the current unwanted behavior. Next, we reflect on whether our preference is a need or a want, and how that interacts with our conception of our identity. Once we’ve detached a preference from our identity, the final step is to examine why we engaged in the behavior in the first place.’
