What is The Turing test?
The Turing test is a way to judge whether a machine can think, proposed by Alan Turing in 1950. If a human judge chatting with a hidden machine can't reliably tell it apart from a human, the machine passes.

Key things to understand
- 1A judge holds text conversations with a human and a machine, unseen.
- 2If the judge can't reliably tell which is the machine, it passes.
- 3It measures convincing behavior, not genuine understanding.
- 4Modern chatbots have reignited debate over what 'passing' really means.
Frequently asked questions
- Who invented the Turing test?
- Computer scientist Alan Turing proposed it in his 1950 paper 'Computing Machinery and Intelligence'.
- Has any AI passed the Turing test?
- Some systems have fooled judges in limited settings, but a clean, universally accepted pass is still debated.
- Does passing mean a machine is conscious?
- No — it only tests whether behavior seems human, not whether the machine truly understands or feels.
