The document discusses six principles of persuasion: reciprocity, scarcity, authority, consistency, liking, and consensus. Reciprocity refers to returning favors and obligations. Scarcity suggests things are more valuable when rare. Authority establishes expertise. Consistency promotes predictable behavior. Liking exploits positive feelings. Consensus finds safety in numbers. The principles were discussed by a marketing professor with a Ph.D. and M.S. in marketing from 2003 to 2009 and 2013 to present at the Indian Institute of Management, Lucknow.
