A typical mind fallacy is when a person projects that other people have the same mind reactions as them.

There is also an atypical fallacy (a much rarer phenomenon). It is the opposite of typical, a person thinks their mind is like no other.

Similar is: mind projection fallacy

is an inability to distinguish between ontology (how things really are) epistemology (how things appearing to you). Person who likes chocolate may equal it with tastiness. Person looking at rock may equal their own experience (photons bouncing of the rock and coming to their eye) with the rock itself (which for the bug with four base colors in the retina (instead of our three) will look different.)
