The antonyms for "more sharing" would be "less sharing" or "withholding." When individuals are less willing to share or choose to withhold information, it can be due to several reasons, including fear, mistrust, or selfishness. In a society where communication and collaboration are essential, withholding information can lead to misunderstandings, conflicts, and missed opportunities. Practicing active listening, empathy, and transparency can promote a culture of more sharing, leading to improved relationships, creativity, and productivity. While it is important to respect people's boundaries, we must also recognize the value of sharing information and resources to build stronger and more resilient communities.
