The more atypical it is to agree to take part the less valid the data becomes.
This is why polls on DS are so much junk.
BARB can't possibly have a cross section of the UK TV viewing population, the process of being "BARBED" is so protracted and invasive that only a few people would take part.
They may very well have a cross-section of social groups, but the people they have must be a bit weird to agree to such a procedure being done to them for very little gain.
