A case of quasi-science

In a world in which a vast amount of biological research is being carried out a great deal of vapid projects will be funded, too. One such as had been a study at Cambridge University using the DNA data of 800,000 people. How much are genes involved when you lose your virginity, or how many children you have?

Because some — but surely not scientists — believe that these depend purely on how you were brought up in the family or due to peer pressure, then this seemed to be sufficient justification for yet another piece of research.

The so-called result — according to the project — was that 25% of sexual and fertility choice is determined by genes and 75% to family upbringing. Apart from confirming what has been obvious to many for a long time and thus not discovering anything new at all, just what do those precise percentages mean?

What if they’d turned out to be 90% and 10%, or 10% and 90% respectively. What difference would they have made? The percentages actually don’t mean anything diagnostically. They mean nothing. It would be cruel to say that it’s pseudo-science but it’s certainly quasi-science and funding would have been better invested elsewhere.
