I want to start with a brief clarification. On rereading this, I’m aware that parts of it may come across as condescending. That isn’t my intention. If anything, what follows is rooted more in confusion and insecurity about my own cognitive profile than in any sense of superiority. Still, I recognize how it might be perceived, so I wanted to acknowledge that upfront.
I’m writing this because I’ve been unable to reconcile the gap between how I perform on cognitive tests and how I function in real life, and I’m hoping someone here has encountered something similar.
My profile is highly uneven. My highest index is FRI at 146, while my WMI is 114. I also took VCI despite not being a native speaker. What stands out is that this variability isn’t confined to testing. It feels like a direct reflection of how I operate day to day.
I also took the 1926 SAT and scored 114, which genuinely made me question my cognitive abilities. I still don’t know how to interpret that result. Is it a consequence of having neglected structured study during high school, given that the test relies heavily on that knowledge base? Is it related to slower reading speed, or test-related anxiety under time constraints? I don’t have a clear explanation for such a large discrepancy.
What makes it more difficult to understand is that the SAT is an outlier in terms of inter-test variability when compared to my CORE results, yet it also displays extreme intra-test variability. I scored in the 95.5th percentile on analogies, while dropping to the 15th percentile in paragraph reading. Quantitative performance was also very low. That distribution feels disproportionate and difficult to account for. In those moments, I find it hard not to conclude that something is fundamentally off, and I end up feeling genuinely unintelligent.
At 17, I was already facing this inconsistency, which became pronounced enough that I started to question my own perception of my abilities. I felt markedly deficient in some areas and relatively capable in others, to the point where my internal sense of “what I could do” no longer felt reliable. That led me to take the Mensa test, largely because it was accessible. I passed, but that didn’t resolve anything. If anything, I’ve since questioned how much weight to assign to that result, given potential practice effects and the structure of the test itself.
Since early childhood, I’ve felt somewhat out of sync with my peers. My interests diverged early, and I often found myself simplifying how I expressed ideas just to be understood. At the same time, my academic performance was highly inconsistent. When I was genuinely engaged, I could perform at a high level with minimal deliberate effort. When I wasn’t, my performance deteriorated significantly.
This pattern repeats across domains. In English, for example, I initially performed very poorly. Later, driven by a strong interest in neuroscience and the need to access English-language material, I developed a high level of proficiency without following a structured path. More broadly, I went through most of school with minimal studying, often relying on inference or pattern recognition, which led to inconsistent results and, over time, a decline in self-confidence.
Math followed a similar trajectory. I was initially failing, then, when forced to prepare seriously to avoid repeating a year, I was able to reach a solid level of competence within a relatively short period. In university, once I systematically addressed gaps in my knowledge, I ended up performing at the top of a cohort of around 300 students. At the same time, in everyday contexts, I can struggle with basic mental arithmetic.
Language shows the same instability. At times, I can express myself with precision and clarity. At others, I struggle to retrieve even simple words, including in my native language. This feels like a retrieval or processing issue.
Attention may also be relevant. I scored 41/80 on the BDEFS, below the ADHD threshold (48+) but not far from it. Subjectively, I have difficulty sustaining attention. A single word can trigger a cascade of thoughts that pulls me entirely away from the original context.
Socially, this creates further inconsistency. There are moments where I’m articulate and engaged, and others where I feel almost blank, as if I have no access to my own thoughts. I’m aware this can make me appear unintelligent or disengaged.
Sleep has a significant impact as well. When well rested, I function normally. When sleep deprived, the decline in performance is substantial. I'd guess even below average.
Overall, my experience feels like a pendulum between two extremes. At times, I function at a high level. At others, I feel markedly impaired.
What stands out to me is that the discrepancy between my SAT and CORE results mirrors almost exactly the inconsistency I experience in real life. I don’t know how to interpret that, but it seems too consistent to ignore.
Does anyone relate to this pattern? Has anyone found an explanation or a way to manage it? Could this point to something like ADHD or another form of comorbidity that doesn’t fully emerge in standard assessments?
I’m trying to understand what’s actually going on, because right now it feels like I’m operating in two different modes without a clear way to reconcile them.
TLDR;
Highly inconsistent cognitive profile and daily functioning. Strong reasoning but large discrepancies across tests (especially SAT vs CORE) and within tests. Every day performance fluctuates accordingly. I'm looking for explanations or similar experiences.
