Judge & Cable 2004 - The Effect of Physical Height on Workplace Success
and Income: Preliminary Test of a Theoretical Model
Type of study: Meta-analysis
Aim: to propose and test a theoretical model on the effects of height on workplace success and income
1. Propose a model of the height–career success relationship
2. Meta-analysis of the height–workplace success literature to test the general implications of the
model
3. Conduct 4 new investigations of the relationship between individuals’ height and their personal
incomes
Theoretical background
• Taller individuals are judged as being more persuasive, more attractive mates, more likely to
emerge as a leader
• Evolutionarily – height = bigger and more dangerous → more power
• Positive relationships of height with performance, leader effectiveness, and leader emergence
THEORETICAL MODEL OF PHYSICAL HEIGHT AND CAREER SUCCESS
• Height → Social Esteem
o Social esteem - how positively one is evaluated or regarded by others in society
(ascribed status, perceived esteem)
o Evolutionarily height means power
o Perceptual bias – people expect a positive relationship between an entity’s size and its
value or status (same as kg of feathers seems lighter than kilo of steel)
o Judging winners of elections as higher and losers as shorter than before the elections
o Language – “big man”, “looking up to someone”
• Height → Self-Esteem
o Height also may affect how we regard ourselves
o Insecurities about height may lead to personalities that reflect stature, perhaps even
resulting in aggressiveness and arrogance that serve as compensatory mechanisms
, o Tall individuals may develop greater feelings of self-worth and self-confidence, because
they are consistently viewed and treated with respect by others → becomes a self-
fulfilling prophecy
o Height was positively associated with external locus of control and emotional reactivity
• Social Esteem → Performance
o Subjective performance
o Objective performance (may be influenced by subjective as well)
o Thus, an individual’s social power and stature may create a self-fulfilling process:
esteemed people are more able to deliver job results that make them even more
esteemed
• Self-Esteem → Performance
o Self-esteem, confidence, and poise are assets on most jobs and lead to enhanced job
performance
o Even when controlling for actual productivity, it is expected that individuals with
positive self-esteem to have higher performance ratings because “self-positive”
individuals are viewed more favorably and are better liked
• Performance → Career success
o Intuitive
General predictions from the Model
1.
a. Height is positively related to ascendancy into leadership
b. Height is positively related to earnings
2. Height exhibits a simplex relationship with status, performance, and then career success, such
that height is most strongly related to status and least strongly related to career success
3. Height is more strongly related to subjective outcomes than objective outcomes
Meta-analysis
• Hypothesis 1a supported → height is positively related to the leader emergence aspect of career
success
• Hypothesis 2 partially supported → data did not reveal predicted differences in the size of the
height–performance versus the height–leader emergence linkage
• Hypothesis 3 supported → subjective ratings (.31) have higher validity than extrinsic measures
(.21), and the difference is significant
• Potential confounding variables - height on earnings:
o Gender
o Age
o Weight
Study 1-4 Results
• Age and height positively predict earnings
• Gender negatively predicts earnings such that women earn less than men
• Age positively predicts earnings
• Weight negatively predicts earnings
