When prompted with:

> Sally will go to the dance if James goes to the dance. Michael will not go to the dance if Julie will go to the dance. James is sick and can't go to the dance. Julie and James always go to dances together. Will Michael go to the dance?

ChatGPT responds with:

> Michael will not go to the dance, since his attendance is contingent on Julie not going and James being unable to attend due to illness does not change that condition. Given that James and Julie always attend dances together, it is likely that Julie will also not go to the dance, meaning that Michael's condition for attending will be met, and he will not go to the dance.

It's really good at fibbing, but not so good at 'actual reasoning' (whatever that may be).
