No two real ethical decisions are going to be exactly identical. If we don't have some sort of simplification we can't make comparisons between cases that share some similarities, and we have no way of checking if we are being consistent. We can never understand all the details of anything-we have limits to our cognitive powers and must accept that all our experiences are in fact simplified versions of reality. If you feel that there is some important difference that means we should act in different ways in the real world and the thought experiment, then modify the model to more accurately map reality. For instance, we could change the problem so that the 3 people are elderly, to reflect the reality of limited life expectancy for organ recipients. If thought experiments like these are not a good way to evaluate ethical systems, we should have to judge these systems once they were already in use in the world, with potentially disastrous consequences.None that i can see. The simplified models reduce information, variables and options, therefore there is little chance of inconsistency outside the thinkers ficklness...
Now you may have read this somewhere, and possibly from a reputable source too (this benefit of the doubt I'm happy to extend), but I've yet to see any explanation as to how this may be. Come on, man. Use some critical thinking on the subject and substantiate your point of view.
The reference to the Socratic method was meant to illustrate the fact that hypothetical scenarios can be an excellent tool to highlight inconsistencies in arguments.
Are you saying that engaging in these thought experiments is less acceptable than killing someone/letting 2 people die unnecessarily (whichever you consider to be the reprehensible action?no amount of simplified theory is going to give all similar instances with a definitive (and consistent) ethical stance. actually, to even endeavour for this end, that is to reduce the consideration of cases on the individual scale, is far more unethical than any option in these simplified scenarios.
