The Marshmallow Test: What Does It Really Measure?
If y = x_0 and x_1 = x_0 + N, then y = x_1 - N. Then y and x_1 are highly correlated. But y - x_0 = 0 – which is not correlated to x_1 at all.
y is "success" x_0 is "socioeconomic background" x_1 is "result of the marshmallow test"

The question isn't whether you can produce example models where "What [vanderZwan says] would only be true if character traits and socioeconomic background were uncorrelated", it's whether it holds in general.
Consider applying for YC's Spring batch! Applications are open till Feb 11.
