Software development with GitHub Copilot is seeing a 50-plus percent improvement.
Mostly true True in substance, wrong in a detail.
Factual: Statements about the present or the past, checked against the record: did they hold up?
The evidence is the person's or their organisation's own records.
Said for an organisation they lead or work for; it counts on both records.
What would count as true or false
Judge as of 2023-11-15. True: published studies available by that date (for example, GitHub/Microsoft research showing developers completed tasks about 55% faster with Copilot) show an improvement of 50% or more in a developer productivity measure from GitHub Copilot, and the claim's generality is reasonably supported. Mostly true: a 50%+ improvement is documented, but only in a controlled study or a specific task (such as task completion speed), which the claim presents somewhat more broadly. Mixed: studies show improvements, some of them 50%+ on certain measures but much lower on others, so that the evidence is roughly split. Mostly false: the 50%+ figure comes from a single narrow experiment (for example, one coding task) and is presented as a general improvement in software development, while broader evidence shows much smaller gains. False: no study shows anything close to a 50% improvement, or the evidence shows no improvement.

“Engineering teams at Duolingo, for instance, have used GitHub Copilot for Business to achieve a 25% increase in developer velocity.”
Reasoning
The GitHub Copilot study (E1) reports that developers with Copilot completed the task 55.8% faster than the control group. That is a published 50%+ improvement on one productivity measure in a controlled setting. The same paper notes that benefits may vary across tasks and languages and that more research is needed on whether the results generalize (E2). That makes the claim broader than the study supports. Another GitHub source from before the judging date reports a 25% velocity gain at Duolingo (E4), and E3 is dated after 2023-11-15, so it was not used.
