Compliments increase happiness

Several studies show that participants underestimated how happy another person would be to hear praise and overestimated how cringe-worthy they would find the exchange. 

• Participants worry they will articulate the compliment wrongly. But the research shows that the recipient only cares how nice the praise is.
• Another fear is that overcomplimenting might make some people bored of your praise or find it tiresome. However, even this reaction is far less likely than we think.
