Having too much confidence is not good. And now, a new study has proved this by finding that overconfident teenage students can stunt crucial（决定性的）reading skills.

The study shows a clear connection between overconfident students and low reading comprehension.

“While some self-confidence is helpful, overconfident 15-year-olds are often below-average (平均水平) readers in all 34 countries we studied, ” says Ming Ming Chiu, the lead author of the study.

“In contrast, under-confident 15-year-olds are more likely to be above-average readers in all 34 countries, ”the expert added.

The difference lies in a student’s ability to exactly assess (估计) and evaluate his or her own reading level, according to Chiu. Those who can accurately assess their strengths and weaknesses are usually in a better position to identify realistic goals and achieve them.

“If an overconfident student chooses a book that is too hard—such as The Lord of the Rings rather than Harry Potter and the Sorcerer’s Stone—he or she might stop reading after a few pages and let it sit on a bookshelf,”says Chiu.

“In contrast, a more self-aware student is more likely to finish an easier book and continue reading more books, ”the expert added.
