Why are a few humans excellent choice makers, whereas others are regularly inept? Why do a little humans stick to their instincts and win, whereas others turn out stumbling into errors? How do our brains rather work-in the place of work, within the school room, within the kitchen, and within the bed room?

We show now the relationship between the interval-valued expectation E(A) = [E*(A), E*(A)], introduced in [90] and the interval-valued possibilistic mean M(A) = [M*(A), M*(A)] for LR-fuzzy numbers with strictly decreasing shape functions. An LR-type fuzzy number A E F can be described with the following membership function [85] 50 1. Fuzzy Sets and Fuzzy Logic A(u) = u - q+) R ( -(3- if q+ ::; u ::; q+ ° + (3 otherwise where [q_,q+] is the peak of A; q_ and q+ are the lower and upper modal values; L, R: [0, 1] ~ [0,1]' with L(O) = R(O) = 1 and L(1) = R(1) = are non-increasing, continuous mappings.
