Question - 1.1: Shall we expect that the irrationality of preferences becomes visible in an Economic scenario where conditions of means and ends ensure that threats to self preservation are lowered to a large degree?
Question - 1.2: If so, how can we observe it in an experimental setting in a lab?
Brief Explanation: Since Id is impervious to experience, and Ego is self preservation, it is logical that under conditions where threat to the self preservation are very low, some glimpse of the irrationality of preferences would be visible. If the environment grants security to self, and credibly promises to preserve each self which is part of it, the need of security would be gratified. And we know from experience when one need is gratified, the preference associated with it dulls in favour of another preference serving another psychological tension, or physiological need etc.
