I'm wondering if anyone has looked at how people's indifference curves can change, whether systematically due to experimental manipulations, or if they just vary due to noise.
I thought about this because of a study I did in which I got violations of transitivity when we generate two options from one indifference curve. For example, let's assume we have these three choices
A[25,50]
B[50,25]
C[45,30]
and a participant is indifferent to the choice sets {A,B} and {B,C}. However, when we present the choices {A,C}, they end up preferring A over C. By indifference curves we mean the line in a 2-dimensional attribute space where any two options are equally preferable. Possibly any study that has looked at violations of transitivity from choices generated from a single indifference curve can address this, but I haven't found anything like that yet.
I think maybe the reason I haven't found anything is that I'm mostly only familiar with the literature in psychology, whereas this seems like an issue what would have been investigated in economics. That is why I am asking about it here.
