AI access drops people's willingness to admit ignorance from 44% to 3%: A study of over 3,000 participants found that having access to AI answers nearly eliminated people's willingness to say "I don't know," dropping it from 44% to 3% in one experiment. Despite the AI being almost always wrong, users felt more confident but were correct only a third as often.

Large Language Models
Developer builds two-model LLM debate system with asymmetric roles
1. Designate one LLM as the 'Thinker' to draft and defend an initial thesis on a complex topic. 2. Configure a second LLM as the 'Challenger' with strict instructions to only ask critical questions and expose assumptions. 3. Feed the Challenger's questions back to the Thinker to force iterative revisions over multiple cycles.
Model Context Protocol
Developer builds MCP server tool to query Google Analytics via ChatGPT and Claude
1. Read the developer's blog post detailing the GA4 Data API quirks and code solutions. 2. Set up a Model Context Protocol (MCP) server to connect external data sources to LLMs like Claude or ChatGPT. 3. Implement custom request-handling code to prevent LLM hallucinations when querying the GA4 Data API.
Prompt Engineering
Direct prompt edit in provider console causes structured output failure
1. Ban direct, one-off prompt edits in provider consoles for production environments. 2. Implement immutable prompt versioning and route all prompt changes through standard source control and evaluation suites. 3. Attach trace metadata to every LLM call to record the exact prompt template version used.
