The Theory

What if you could think without any sensory support at all — no inner voice, no mental images, no bodily feelings? Just pure reasoning about relationships, structures, and propositions. Mathematicians have reported this for centuries: Hadamard surveyed top scientists and found that many described their creative process as operating on abstract structures with no sensory form. For people with both aphantasia and no inner speech, this is not a special talent — it is their everyday reality. They reason about concepts "naked," without the clothing of words or images.

What the Research Found

Hurlburt's rigorous experience-sampling studies documented that some people regularly experience unsymbolized thinking — genuine thought with no sensory representation whatsoever. Zeman's 2020 work showed that aphantasic individuals compensate by developing abstract-propositional strategies that are functionally effective, just differently organized. Hadamard's classic survey of mathematicians and scientists revealed that many reported thinking in terms of abstract relations and structures, with words arriving only later as a translation step for communication.

How We Use It

Question A1 option (e) — "There's nothing specific: no words, no images, no sensations. It's pure, abstract reasoning with no form" — directly captures abstract-propositional thinking (dimension value 1.5). A2(e) maps the nocturnal insight that arrives as formless knowing, A3(e) captures system understanding as abstract rules, and A5(e) describes reasoning through logical implications without sensory involvement. Consistent (e) answers indicate your cognitive channel is abstract-propositional, the mode Hadamard documented among mathematicians.
