Influence: The Psychology of Persuasion by Robert B. Cialdini
Influence!
|
Influence is an influential book - and it has permeated high-tech.
For example, Joel Spolsky referred to it in a post on the
influence that Microsoft were attempting to secure in the great Vista
laptop blogger giveaway (Bribing Bloggers).
A very short summary of the principles of influence follows:
-
Reciprocity
-
People try to repay favors - even when the repayment is
unequal - free coffee in the car showroom and complimentary
give aways at the supermarket are examples the potential
for the generation of unequal feelings of indebtedness
that we should be cautious of.
-
Commitment and Consistency
-
You have spent time in a given state and to change
behavior would imply an inconsistency
-
Social Proof
-
What is in fashion with other pepole?
-
Liking
-
We are likely to follow the suggestion of
people like ourselves whom we know and like.
-
Authority
-
People in white coats in the laboratory are
the only trusted source for information about
nutraceuticals
-
Scarcity
-
We are programmed to survive famine and, as the
collectors know, possessing the completing
item in the set can be overwhelmingly influential
If you have ever marvelled at the ability of everyone around you to
spend inordinate amounts of money on 'plush' dolls, trolls or
manufactured pop idols - this is a useful and explanatory book. The
utility of the book is in exposing the strands of attack of the
influencer - these are normally fairly obvious - but it is interesting
to have the examples and the categorizations that Cialdini provides.
It is also troubling to read of the potential consequences of
influence in its most extreme and dire manifestations.
