Thinking about the pitfalls of EU-wide surveys yesterday reminded me of one with which I was involved in the 1970s
For good medical reasons we needed to include a question about alcohol consumption. The question needed to be kept simple (for translation reasons) & we decided on a simple high/medium/low type format
Then we had to define our terms
The Italian representative was of the opinion that low should mean less than 2 litres of wine per day
Hows that for a Mediterranean diet?
