G - Gaslighting
When someone systematically causes another person to doubt someone else's perception.
Recognizable questions Why do I doubt my own memory after conversations? When is a disagreement gaslighting and when is it not? How can I separate facts and interpretations? What is it? Gaslighting is a pattern of manipulative behavior in which someone repeatedly tries to make another person doubt their perception, memory, or sanity. A single difference in memory is not gaslighting; it involves a recurring pattern and power dynamics. Why can our brain do this? When someone who is important to you denies your experience with great certainty, that can be confusing. Social dependence, trust, and power differences can intensify that doubt. Example from everyday life A partner repeatedly says: ‘I never said that, you’re making things up’, while messages exist that confirm the conversation. Over time, the other person becomes less willing to trust their own memory. How can this occur within close or closed groups? In groups, members and critics can sometimes accuse each other of ‘distorting reality’. Not every doctrinal change, mistake, or disagreement is gaslighting. The term is most useful when there is a pattern in which someone’s perception is deliberately or systematically undermined. What can you do with it? Write down important facts and agreements. Seek reliable, independent information. Discuss recurring doubt with someone who is not directly a party to the conflict. Questions to think about Is this one difference in memory or a pattern? What verifiable facts are there? Am I being encouraged to investigate clearly, or mainly to doubt myself? Summary Gaslighting is a specific form of manipulation and should not be used as a label for every conflict. Facts, patterns, and context matter.
