Quantification of fairness bias by
a Fairness-Equity Model
David Nicoladie Tam

We have developed a computational model that quanti-
fies fairness objectively based on equity/disparity
between the shares by two individuals. This Fairness-
Equity Model  represents the relationship between
fairness perception intensity and the disparity (or equity)
between two individuals graphically. Fairness bias is
represented by what is considered as equitable between
the shares. Absolute equity represents equal shares,
while relative equity represents unequal shares. Toler-
ance to inequity is represented by the unequal share, yet
considered as fair. This represents fairness bias, in
which inequitable share is tolerated as fair. This toler-
ance for inequity can be represented graphically by the
fairness-equity graph by shifting the fairness-curve hori-
zontally. Sensitivity to fairness or unfairness can also be
represented by the increasing the slope of the fairness-
curve. Fairness perception is also hypothesized by the
proportionality relationship to the equity/disparity
Confirmation of this proportional hypothesis is pro-
vided by using the Ultimatum Game (UG) with human
subjects. The results show that fairness perception is
proportional to the equity/disparity signal. The fairness
biases are also quantified the shifting of the fairness-
curve relative to the acceptance and rejection decision
in the UG experiment. It further reveals the objectivity
of fairness perception to equitable share compared to
the subjectivity of fairness perception to inequitable
