Actually I'm trolling. I'm trying to get some members of the biologic research community to do a little self-examination. I don't know much about the subject, but here is what I do know (now that I have been pushed into articulating it):
1. We are doing more biological research with what are basically 19th century approaches involving the death, pain, and mutilation of animals than we need to be doing. We do not know how much more (which is covered in greater detail in point 3)
I'd really like you to back up that "19th century approaches" claim.
2. To do this, we are training grad students, lab techs, and sometimes undergrads who need a biology credit in the intensive use of the ego defense mechanisms of "clinical objectivity" or "clinical detachment." Which is also the conscious suppression of normal human empathy. There is little to no screening done beforehand to determine if these persons have the emotional maturity and self-insight to limit the use of these mechanisms to the biology lab. There is no follow-up of these individuals; not even the ones who are given their walking papers because they are too unbalanced to do the work properly. Yet the clinical detachment that is needed to handle lab animals creates serious problems when it is used inappropriately in relationships, with children, in an office setting, among colleagues, etc.
You obviously shouldn't get emotionally attached to lab animals for a variety of reasons (not all bad ones). But people are good at compartmentalizing. As for your accusations about clinical detachment do you have any evidence for these claims?
3. No one in the biology research field is even seeing this as a problem. Despite the mass murders of the last few years, where the mechanisms of "clinical detachment" are taken to the pathological extreme. There is no discussion of whether it is time to start limiting training in these techniques, no discussion about how to reduce the number of individuals affected, there is not even an attempt to determine the scope of the problem. The closest is the USDA figures on the number of selected lab animals in active use in the USA: that is 1.3 million. But it excludes rats and mice and animals being bred for scientific use but not yet put to that use. The number of lab animals that lab techs and grad students are exposed to in this country has been estimated at between 10 and 50 million. But even with the 1.3 million figure, that is a large pool of persons being trained in the skills of clinical objectivity (with nothing being done to assure that they are capable of appropriately using those skills, or prevented from maybe obtaining a fully automatic rifle if they are not capable of policing their own psyches).
What seems to be necessary is to push the individuals in the biology research community into confronting the absurdity of their rationales and deliberate blindnesses, and get them looking for ways to move the research animal labs out of the 19th century and into the 21st century. Agitating for laws that would enforce limits upon the research communities seems to be necessary, just to get their attention.
Whether such laws are needed is a topic that is open for discussion. That the research community must be pushed into doing a scientific study on the effects of its practices on the psyches of its minions is definitely necessary.
Again all you've done is speculate, you've shown absolutely no evidence for psychological damage among researchers, you haven't even found an anecdote of some spree shooter being a biologist. People can eat meat without being sociopaths, they can look at cows in a field without being sociopaths, why are you assuming they can't deal with lab animals and avoid emotional attachment without incurring a mental illness?
