Question

How can psychology help businesses?

Answer 1

Business are run by people, and people are affected by many issues that ultimately impact performance and stress.  Industrial/Organizational Psychology is the subdiscipline that researches links in organizational behaviour.  It is through psychology that work conditions have improved, HR departments fairly assess, select, and promote the best candidates for the job.  Morale has increased in designing jobs through job analyses (also psychology in breaking down knowledge, skills, abilities).  The list goes on.  

Answer 2

Psychology can help business people figure out what people want, and then they can work at giving it to them.  Or, these days, it is more a matter of figuring out how to make people feel that they need what the business is selling. I would call this "pseudo-needs."
