There are many synonyms for the phrase "half truths", all of which have slightly different connotations. Some include "partial truth", "incomplete information", "selective disclosure", and "misleading truth". Each of these phrases indicates that there is some truth to what is being said, but that there is also important information being left out which could change the overall picture. When someone deliberately uses half truths to avoid telling the whole story, it can be frustrating and misleading. It's important to always seek out the full context and all the available information, especially when making important decisions or judgments based on what we are told.
