I'm always amazed by human psychology. Speaking of this, here are three psychology effects everyone should know. These are hacks to request a favor, become more likable, and get the help you need.
1. The Franklin Effect
People like you more when they carry out a favor for you. However, the effect has its limitations and is more likely to work with small favors rather than more significant requests that either make people respond begrudgingly or, even worse, refuse.
2. The Pratfall Effect
The occasional slip-up can enhance your likeability. However, it is important to realize that the effect only really works when you are in danger of being seen as too perfect.
3. The Bystander Effect
The more people who are around when a person is apparently in need of assistance, the lower the likelihood of any one person actually helping. If you are unfortunate enough to require assistance, increase your chance of getting help by picking out a friendly face in the crowd, and be specific with your problem you have and assistance you need.
