Standards explain to new hires how to "fit in" w/their co-workers. 

New hires want to fit in and they will emulate the behaviors they see rewarded. 

Key points 

• If you hold disadvantaged workers to lessor standards - you handicap their ability to fit in. 
• People learn by watching others - use standards to identify role models 
• People have a basic desire to fit in - if someone wants to be accepted they try to perform up to the standards
