“The stereotype of women’s limited parking skills is deeply anchored
in modern culture.” But has rarely been scientifically investigated,
prompting Claudia Wolf, M.Sc. and Sebastian Ocklenburg M.Sc.
and colleagues at the Fakultät für Psychologie, Institut für Kognitive
Neurowissenschaft, Abteilung Biopsychologie, Ruhr-Universität Bochum,
Germany, to perform an experimental study.

65 participants (30 women, 35
men) were tasked with parking an Audi A6 (automatic) in both bay-parking and parallel-parking manoeuvres in a closed-off multi-storey carpark. And, perhaps reinforcing the stereotype, differences did emerge : “The
present data revealed a sex difference in parking performance in
driving beginners as well as in more experienced drivers. Across all
three types of manoeuvres, men were 2.4% (range 1.7–3.7%) more accurate,
and 35% (range 30.4–37.3%) faster than women.”

Allowing inferences to be drawn  “… an analysis of parking abilities
is able to uncover how possibly biologically rooted sex differences in
spatial cognition could develop into differences between groups that are
modulated by socio-psychological factors.”

‘Sex differences in parking are affected by biological and social factors’ is published in the journal Psychological Research (2010) 74:429–435 (And can be read in full here )

p.s. “Additionally, the
prevalence of the prejudice about women’s parking skills could
constitute a stereotype threat that additionally decreases women’s
performance.” (from the university’s press release site which mentions the study.)
