the usual: if we can handle this case before the try/except that would be preferable

@jbrockmendel I’ll give that approach a try.

@jbrockmendel Pushed an alternate approach that escapes from the _try_convert_to_date() method if the dtype is bool, avoiding the try/except but adding a conditional to the method (which I don't love, but at least the method already has dtype-based conditionals).

yes this is ok. an alternative approach is to infer_dtype on this and then dispatch. If someone wants to try that (later PR) would be ok.

Can you move this to test_pandas and add GH 31464 as a comment in the function body?

Done

result = read_json("[true, true, false]", typ="series")
