How do we know smoking causes cancer without experimenting on people? Epidemiology: studying disease patterns across whole populations. Descriptive, analytical and intervention studies each answer different questions with different strength. This is the real knowscape from knowhere, not a picture of one. Drag it. Watch what actually changes.
You can't run the experiment — you can't give people cancer to prove a cause. So epidemiology reads the population instead: patterns, rates, and correlations across whole groups, then argues from strength, consistency, and dose whether the link is causal. Every study is that same argument, built without a lab.
Epidemiological studies identify disease causes and risk factors by analysing patterns in populations through descriptive studies (what/where/when), analytical studies (comparing groups) and intervention studies (testing preventions).
knowhere maps every concept to what it rests on and what rests on it — 0 underneath this one, 1 built on top. Each one says why, in a sentence, not as an arrow on a diagram.
Each one is its own knowscape in the app — built for how a particular student takes things in, not one explanation handed to everybody.
