How does Freakonomics show the link between training and strategic alliances?

Chapter 2 of Freakonomics primarily
discusses the importance of strategic alliances, especially in regards to obtaining the
best information to perform one's job. The chapter features Stetson Kennedy who was able
to use strategic alliances to infiltrate the KKK and glean significant information from
them in order to expose the way the group worked. Kennedy maintained an alliance with
someone who was believable enough to be accepted by the Klan and also an alliance with a
radio host in order to disseminate the information that he obtained. In doing so, he was
able to assist in neutering the Klan from what it was in the early half of the 20th
century.

In regards to training, the second chapter also
focuses on real estate agents and their use of alliances, insider information, and
precise diction to get the best possible commission from each sale. It takes time and
experience for a real estate agent to be "trained" in how to word advertisements.
Similarly, a successful real estate agent seeks beneficial associations with other
businesses, agents, and clients in order to study how a sale can best be brokered to
suit the agent, even if that means encouraging a client to lower a selling price in
order to sell quickly.
