The effects of personality and intelligence on economic behaviour in a samp
le of 207 Scottish farmers were investigated. Data were available on the fa
rmers' attitudes, objectives, and business-related behaviours, together wit
h personality trait and cognitive test scores. Structural equation models o
f production-oriented business behaviour and environmentally oriented behav
iour were constructed. It was found that farmers who score highly, on Extra
version (E), Openness to Experience (O), Conscientiousness (C), and cogniti
ve ability are more likely to show production-oriented behaviour and that t
he effects of personality and cognitive ability are mediated by a more open
attitude towards farming. For environmentally, oriented behaviour, high sc
ores on E, O, C, and cognitive ability were associated with this behaviour,
with mediation by an achievement-oriented attitude to farming, chemical us
e attitude, and off-farm/diversification objectives; there was also a posit
ive effect of Neuroticism, mediated by pessimistic attitudes to farming and
off-farm/diversification objectives. These results show that that personal
ity, and intelligence have substantial and measurable effects on farmers' e
conomic behaviour. Copyright (C) 2001 John Wiley & Sons, Ltd.
