Can you prompt your AI into telling the truth? I tested it

Software developer Scott DeSapio recounts conversations with Claude Opus 4.6 in which he pushed the model to commit to direct honesty, wrote a workspace rule against hedging, and then had it name Objectivism as the source of the rule's principles, with the agent admitting a trained bias against the philosophy. He then opened a fresh chat with both rules in place and asked the model about Objectivism cold, presenting the results as a test of whether prompting can override default agreeableness.
