The Guardian has got hold of the following academic research:
"On a party-by-party basis, the average (childhood) IQ scores for 2001 voters were:
Green – 108.3
Liberal Democrat – 108.2
Conservative – 103.7
Labour – 103
Plaid Cymru – 102.5
Scottish National – 102.2
UK Independence – 101.1
British National – 98.4
Did not vote/None of the above – 99.7"
What do you make of that then?
