Gwern notes Calhoun hardly piblished anything formal (much less peer-reviewed) about his research - mostly interpretation-heavy summaries of what he wanted to emphasize. Not enough detail rigorously 'replicate'! But Gwern does mention a few followups that tried similar setups - and didn't really see the same major takeaways. So "nobody has tried" isn't really accurate. Nobody has succeeded!
