I feel the need to point out that nor "data" or "conceptual designs" are living beings, much less part of an animal species. Therefore I cannot agree with the perspective that such things could fit within the category of "spirit animals". Thought since every person is different in their own ways despite sharing the same type, it's impossible to assign a single animal species to be a perfect analogy for every single one of the characteristics that make up our collective personalities, so trying do so is pointless to begin with. Variables, variables. Why are we comparing animals with people anyways?
Ah, whatever, just say it's an owl like everyone else and indulge in unhealthy nocturnal-like sleeping habits. Also, you could try posting threads directed to INTPs into the INTP subforum, you'd get more exposure there.
