The original headline isn't inaccurate, though it is clumsily worded and neither it nor your proposed headline fully describe the results of the study. The study itself says the following (quoting verbatim). Note that the second point is more or less what the headline says. - Self-regulation composite (preschool & ages 17-37) predicts capital formation at 46. - Preschool delay of gratification alone does not predict capital formation at 46. - The composite is more predictive partly because it consists of many items. - No evidence of more predictive power for self-regulation reported later in life.
