The ability to delay gratification exists on a continuum and is predictive of certain aspects of success, according to a review of the marshmallow test studies posted by @hubermanlab. The post states that critiques of the two-marshmallow test have themselves been misrepresented and that most people do not cite the studies correctly.
It outlines what the actual experiment measured and what the data showed.
The original studies, conducted at Stanford in the late 1960s and 1970s, presented preschool children with one marshmallow and the option to wait for a second if they resisted eating the first. Follow-up data tracked participants into adolescence and adulthood.
Researchers found that longer delay times correlated with better outcomes on selected measures including academic performance and behavioral adjustment.
The post emphasizes that the trait operates on a spectrum rather than as a binary ability. Subsequent replication attempts and larger studies have produced more nuanced findings, with socioeconomic factors and environmental conditions influencing results.
The @hubermanlab post argues that popular dismissals of the test often overlook these details and the specific predictive relationships reported in the original papers.
The account concludes that delay of gratification remains a measurable individual difference with meaningful, if qualified, links to later outcomes.
