Insight by Culture
There are practical economic limits to increasing cargo ship speeds because pushing above roughly 15 knots requires disproportionately more fuel and operating costs, so average viable speeds have stayed around that level.
Every card on Korva is an insight someone saved from a podcast or video they loved.

See all →Familiarity produces a rapid, preconscious 'flicker' of recognition because ease of processing triggers quick semantic signals that feel like correct intuition before conscious thought catches up.
Secondary hubs appear when a region produces enough demand bound for a particular destination that it can fill dedicated flights, so carriers run direct regional services instead of routing through the main hub.
Repeated exposure makes unrelated statements seem true because repetition creates familiarity that reduces processing effort, and that feeling of ease is misread as a signal of truth.
Before containers, 'break bulk' loading was extremely slow because every item had to be carried into ship holds piece-by-piece, so loading a single ship could take more than a week.
Frequent exposure makes nonsense words or meaningless stimuli feel positive because familiarity triggers cognitive ease and positive affect, which people interpret as favorable meaning.
FedEx bases its SuperHub in Memphis because the city sits near the U.S. mean population center, which minimizes average distance (and therefore transit time) to the largest number of customers.
When information is processed with little mental effort it produces cognitive ease, and because the brain uses that ease as a quick heuristic it leads people to judge things as true, likable, or safe.
Regional hubs like Oakland exist because routing every package through a single SuperHub would add long detours and fuel use, so regional hubs provide shorter, more direct routings for strong regional flows.
