hmm... insurance is a vital part of our economic and banking systems.
Of-course there are many kinds of insurance that could be managed much more effectively given better understanding of risks associated with particular genetics. Why should insurance not take DNA research and profiling into account? Indeed, how could it not?
Here's the problem.
The whole point of insurance is to spread the risk. Everybody pays in a small amount in the knowledge that they are probably going to lose money on the deal but there is a chance they will have to make a claim and without the insurance, it would bankrupt them.
However, if you know you won't need to make a claim, you won't buy insurance which means the subsidy the insurance company gets to cover the people who will be making claims goes away and the premiums of high risk people go up. This is one reason why Obamacare made it mandatory to get health insurance.
Conversely, if the insurance company knows you will be making a claim, they are not going to enter into the deal unless your premiums will cover the claim.
At some level of knowledge, insurance stops being insurance and starts being a savings plan. Unfortunately, because of the high costs it would be expected to cover, the payments would be too much for most people.
The benefits of everyone having their DNA details to hand will be enormous and surely the possible threats to civil liberties can be managed with appropriate legislation and systems design?
We live in a country where the HMRC lost a CD-ROM with everybody's child benefit details on it and a country in which the Home Secretary is telling us we don't really want end to end encryption. I wouldn't trust the government with my DNA. The only people I would trust less than the government with my DNA is for profit corporations, like insurance companies.
