>>44177233>Human Intelligence or GreaterSo this is asking if the creature is sapient and has higher intelligence. This is important when it comes to equality. If the person is not as sapient as you its not morally right and is possibly illegal dependent on your community.
>Can it talk or otherwise communicate with langaugeSo this one should say "Can it communicate in a language you both understand". Communication is an important aspect of consent, though consent itself is a legal matter not simply a "moral" one. In some places in reality its okay for a 12 year old to morally and legally consent to sex even though in a large majority of the world that's not moral and also is illegal. Getting into matter 3 here, so basically being able to understand one another is important yes.
>Is it sexually mature for its speciesThis needs to be reworded. Humans are sexually mature by like 13 or so, but its still illegal in most of the world to have sex at that age. This question should say "Is it of legal sexual maturity for its species, in its community?" that's more important. When dealing with Pokemon a newly hatched Torchic can have eggs so its of sexual maturity at birth, but that doesn't mean its community or culture will be okay with them breeding/having a mate yet.
So with all that in mind? The Harkness Test is not completely moral as it's phrasing in some questions need a little rewording.
