Our tendency to believe we know more than we do illustrates is "overconfidence".
Overconfidence alludes to a biased method for taking a gander at a circumstance. When you are overconfident, you misinterpret your esteem, sentiment, convictions or capacities and you have more certainty than you should given the target parameters of the circumstance.
Overconfidence can make a man encounter issues since he may not plan appropriately for a circumstance or may get into a perilous circumstance that he isn't prepared to deal with.
