Benjamin Lhanghal didn't set out to write a book about intelligence. He set out to answer a question that had bothered him for a long time. why do so many brilliant people underperform, and why do so many people written off as average end up doing remarkable things?

The answer, he found, had nothing to do with IQ.

It had everything to do with the other four forms of intelligence that nobody talks about — Creative Intelligence, Executive Intelligence, Metacognition, and the adaptive capacity he calls 1% Intelligence. Each one real. Each one measurable. And each one something you can actually build.

the author writes at the intersection of psychology, neuroscience, and human potential — not for academics, but for people who are genuinely curious about how their mind works and what it is capable of. His writing is research-backed but never dry, and always aimed at one thing: giving the reader something they can actually use.

5 Levels of Intelligence is his first book — written for everyone who was ever told the number wasn't high enough, and never quite accepted that as the final word.
