Law of the Instrument – when one tool feels like the answer to everything
When you have a hammer, does everything look like a nail? That’s Law of the Instrument – the tendency to over-rely on familiar tools or methods while ignoring better alternatives.
Where it can show up
- Work – you apply the same approach to every problem, even when it’s ineffective.
- Management – you rely on strict deadlines for everything, forgetting that flexibility can be key.
- Technology – you always use your favorite software, even when a different tool would work better.
A practical countermeasure
- Focus on the problem, not just your usual method – not everything can be fixed with one tool.
- Learn new approaches – maybe you just haven’t explored more effective solutions yet.
- Be adaptable – if something isn’t working, you need a different tool, not more force with the same one.
