2014 AM Q11 Behavial Bias

I udnerstand the two biases selected for him (representativeness and availability), but why is self-control not identified as one of the biases for Lam?

It states that “Lam has been saving for several years but is behind schedule to ultimately fund his retirement.”

didn’t the question ask for cognitive?

The fact that you don’t have enough saved doesn’t mean you exhibit self control bias. You could not have enough saved because of surprise extraordinary expenditures in your past or a million other things.

If they want to point you towards self control bias, there’ll be a question where the person being described always pursues immediate gratification at the expense of long-term saving. Expensive vacations, cars, etc.
