The [https://www.agcas.org.uk/write/MediaUploads/Resources/ITG/iceberg_metaphor.pdf iceberg metaphor] is a famous metaphor sometimes [https://pubmed.ncbi.nlm.nih.gov/31633371/ misattributed to Freud]. Just as real a iceberg floats with the vast majority of its body below the water's surface (often simplified as 90%, which does quite closely reflect the general range of buoyancy for ice in cold sea-water), the iceberg as metaphor represents a system where the large majority is unseen, invisible, or hidden in some way.

In this case, Ponytail is using it to illustrate the fact that about 95% of the mass in the universe does not appear to be in the form of ordinary ("{{w|baryonic matter|baryonic}}") matter, but rather {{w|dark matter}} and {{w|dark energy}}. Dark matter is known to not interact at all with ordinary baryonic matter except by gravity, and has been detected only by its gravitational effects. Excluding dark energy, dark matter accounts for about 85% of the total mass of the universe. So baryonic matter is like the "tip of the iceberg," visible to us above the surface, while dark matter is like the invisible majority of the iceberg below the surface.

The questioner in the audience misunderstands the metaphor by taking it literally, thinking that Ponytail is saying that the part of an iceberg below the surface is literally made of dark matter. He points out that the {{w|Titanic}} sank after its hull was damaged by hitting the underwater part of an iceberg, which wouldn't be possible if it were made of dark matter.

The title text references the myth that we use only 10% of our brain, and we could become more intelligent or powerful by "unlocking" the remaining 90%. If icebergs had brains, and the 90% in the "dark matter" part underwater used only 10% of its brain, while the tip also used 10% of its brain, then most of the cognition would occur in the underwater part. Hence the "9%" figure would refer to the cognition occurring underwater, with 1% of its cognition occurring above water. In reality, human beings use pretty much all of their brain. They just don't use it all at the same time. The effect of using one's whole brain would depend on precisely what is meant by that -- for example, all excitatory neurons firing with no inhibition for a prolonged period would be a {{w|seizure}} (most likely fatal), but there's no reason to exclude inhibitory neurons and adenosine when "using all of one's brain at once".

:[Ponytail is standing on a rostrum and pointing to a chart with a stick. The chart depicts a cross section of an iceberg in water, so most of it is underwater, depicted as light gray in dark gray water, but a little is above the surface, depicted in white. There are labels above and below the drawing with two small arrows pointings from above and below to the two segments of the iceberg. An off panel voice speaks from a starburst at the right edge of the panel.]
