J.S. Wilde is Professor Emeritus of Psychology at Queen's University in
Kingston, Ontario, Canada. Born in the Netherlands in 1932, he received his
Ph.D. (cum laude) from the University of Amsterdam in 1962. He was visiting
professor at the City University of New York 1964-65, and has been Chairman
of various research groups of the OECD. He has been active in research and transportation
safety since the late '60s and has received visiting scientist's awards from
the governments of France and the Netherlands. His teaching and research interests
include ergonomic psychology, skill acquisition, mass media messages and behaviour
change, human behaviour in transportation, and the psychology of risk taking.
TO TAKE A RISK:
to expose oneself to potential loss.
[from Latin risicare = to navigate around a cliff or rock]
the level of risk a person chooses to accept in order to maximize the overall
expected benefit from an activity.
[Synonyms: accepted, preferred, tolerated, desired risk; set-point risk]
a regulating process that keeps the outcome close to the target by compensating
for disturbing external influences. For example, the human body core temperature
is homeostatically maintained within relatively narrow limits despite major
variations in the temperature of the surrounding air.
[from Greek homeo = matching, similar, and stasis = condition, state of affairs]
the degree of risk-taking behaviour and the magnitude of loss due to accidents
and lifestyle-dependent disease are maintained over time, unless there is a
change in the target level of risk.
of First Edition
(now out of print and replaced by “Target Risk 2” (2001), with
more empirical evidence.)
This book is dedicated by a boyhood friend to the memory of Damiaen van
Doorninck, Jacques Jansen, Hans Cohen and Izaäc Gosschalk, who fell victim
to the violence of fascists, and offered in lasting gratitude to the Canadians
who liberated Deventer, their hometown in the eastern Netherlands, from Nazi
tyranny on the tenth of April in 1945. All are immortal: the dead live on
in the lives of the living.
