The antonyms of "most disclose" can be defined as hiding, concealing, withholding, or obscuring information or evidence. These antonyms suggest that individuals or organizations deliberately choose not to reveal certain facts, details or truths. They may do so for a variety of reasons, such as protecting their reputation, avoiding legal concerns, or preserving their privacy. In contrast, when individuals or organizations opt to disclose, they often promote transparency, honesty, and integrity. It's worth noting that in some cases, keeping some information secret is necessary or even preferable. However, when it comes to important matters such as public safety or social justice, "most disclose" should be the guiding principle.
