My most common advice for junior researchers
Viral post details three critical habits to prevent wasted months of research on flawed ideas.
In a widely shared post on the AI Alignment Forum, researcher LawrenceC distilled his most frequent feedback for junior collaborators into three essential habits, with the first being the critical practice of 'quick sanity checks.' He argues that research is inherently difficult and researchers are often wrong, leading to wasted weeks or months on fruitless investigations. This waste can be prevented by implementing basic validation steps early on. These checks involve questioning if an idea fundamentally makes sense, identifying obvious data biases or incorrect prompts, and ensuring theoretical claims are substantive and not vacuous.
LawrenceC provides concrete, AI-focused examples of these sanity checks. For instance, when studying LLM agents, researchers should quantitatively understand their data: How many tool calls are made? How many succeed? He cites past research where broken scaffolds led to complete agent failure. Another key check is creating small, concrete examples. When testing an algorithm like A* search, does it work on a simple 4-node graph? When claiming a similarity measure is a metric, does it hold for three concrete points? The post warns against taking this advice to an extreme, emphasizing that the checks must remain 'quick' to avoid becoming a procrastination tool, but when applied correctly, they are a fundamental defense against major, time-consuming errors.
- Perform 'quick sanity checks' on data and assumptions to avoid wasting months on flawed research.
- Check for data bias, basic correlations, and algorithm functionality on small, concrete examples (e.g., a 4-node graph).
- The advice, from a viral AI Alignment Forum post, is the first of three core habits for effective research.
