Personnel: Jan Leike at Google DeepMind (Research Scientist)

Verdictcontradicted95%
1 check · 4/9/2026

The record claims Jan Leike was a Research Scientist at Google DeepMind with dates 2017-2021. However, the source text states he was 'an alignment researcher at DeepMind' (using past tense without specifying 2017-2021), and explicitly states this was 'Prior to OpenAI.' The source also mentions he 'co-led the Superalignment Team at OpenAI' and currently 'lead[s] the Alignment Science team at Anthropic.' The source does not confirm the specific role title 'Research Scientist' or the date range 2017-2021. Additionally, the organization is listed as 'DeepMind' in the source, not 'Google DeepMind' (though this is a minor naming variation). Most critically, the source provides no evidence that his DeepMind tenure ended in 2021 or began in 2017—it only indicates it was prior to his OpenAI role.
