Unconvinced by the DAGs

(NB: for those out of towners.
'dag': the dried bits of excreta around a sheep's tail; an expression used by Australians to refer to someone who is great fun and unconcerned by what others think; a geek who likes Barry Manilow records)

Normally I have a lot of time for ABC Radio but today they came up with this which is the biggest load of 'horsesh*t' I have heard in some time!

Apparently the difference between how much emotion a song expresses and how much emotion is felt by the listener is rateable on a scale (what???) and the bigger the 'Differential Affect Gap'
(DAG) the less likely the person is to like the song.

Well no sh*t Sherlock!!!!!!

The eminent professor goes on to say that the amount you like a song will depend on your age, personality and taste and that some songs have a low DAG factor in one demographic but not in another.

Well, IS THE POPE CATHOLIC?????

And the Government is funding this research?????

NB: No mention is made of the obvious correlation between the proportion of excess emotion expressed in songs such as 'All By Myself' (Eric Carmen) and the vomit factor.
