If a person always considers only himself right in work what effect will it have on collective decision making?

Correct answer: Useful information from others may be missed

The direct answer is Option A: useful information from others may be missed. Collective decision making means that several people share facts, experience, and suggestions before the group chooses. If one person always thinks only he or she is right, that person may refuse to listen, reject corrections, and give no proper value to another member’s knowledge. Step by step, the attitude reduces listening; reduced listening hides useful information; hidden information makes the final decision weaker and less cooperative. Option A is correct because it describes this exact harm. Option B is wrong because equal inclusion requires respect and listening, not stubbornness. Option C is wrong because group learning usually decreases when discussion is blocked. Option D is wrong because a decision cannot be fully fair when some views are ignored. A skilled person should also remain humble. Memory cue: good teamwork needs both knowledge and willingness to listen.
