We generally think Trust once broken, is hard to regain or it can be never regained. But the new research says, its all depends on the mindset of the individual.
For E.g.: If you are going for a negotiation with a person bearing in mind that he/she already deceived you in the earlier negotiation, then chances are very high that whatever he/she does you will end up feeling deceived even if there are valid reasons behind your negotiation not coming out as fruitful.
Hence, always have a growth mindset. People with a growth mindset are more likely to overcome negative stereotypes, are more creative, and ultimately tend to be more successful.
Unfortunately, deception is common, and if you are deceived it is wise to update your perceptions quickly. You can always change your opinion of someone again, if they prove themselves more reliable in the future. Believing that change is possible has a number of benefits.
So if you tend to believe people’s characters are stable and fixed, try to notice those times they surprise you. Everyone can change – including you.
