Summary of “To Seem More Competent, Be More Confident”

One important reason this happens is that people are simply not great at assessing competence – a crucial trait for succeeding at work – and perceptions of competence are just as important for success as actual competence.
Because of this, people tend to evaluate competence based on other factors, meaning you have to do more than produce results to convince them of your expertise.
Lo and behold, the person’s prediction had a strong influence on how subjects perceived their competence: Observers evaluated those who made optimistic predictions as much more competent than their modest contemporaries – no matter how accurate those predictions were and how well they actually performed.
A negative forecast may lead you to be perceived as distinctly less competent – no matter how well you actually perform.
Why do people view confident others as more competent, even when their performance suggests otherwise? One explanation is that we have a tendency to believe what we are told, and to confirm our beliefs by selecting information that supports them.
To feel more authentic demonstrating confidence, you may first have to convince yourself.
Do you think they have a good sense of your competence and expertise? If not, could you be demonstrating more confidence in your tasks? This doesn’t necessarily mean praising yourself at every opportunity; rather it means projecting an optimistic attitude.
By displaying more confidence in your abilities, you set yourself up to be recognized for your competence and your contributions.
