Why is this week unlike every other week?

A clever new study in the journal Addiction provides clues about who is worst at owning up to the full extent of their drinking.
The researchers surveyed over 40,000 people with standard alcohol survey questions about their quantity and frequency of alcohol consumption — “How many drinks have you had in the past month?” and so on. But in a smart twist, they then asked a more immediate question: “How many drinks did you have yesterday?”
I’ve written about this technique before; it can be very powerful, though it won’t help much if people are intentionally misleading you.
