Principle of Least Effort<br />
Basically, when a person applies a tool to a job, he or she tries<br />
to minimise the effort to achieve an acceptable goal<br />
Example – speech communication<br />
– Goal is to exchange information<br />
– Speaker would prefer minimum effort (minimum<br />
articulation, vocabulary etc)<br />
– Listener would prefer careful articulation, detailed &<br />
specific vocabulary<br />
– Feedback from listener indicates success of failure of<br />
communication<br />
