Causation between states or only between measurements?

In summary, causation between states refers to a direct cause-and-effect relationship between two variables or phenomena, while causation between measurements is a statistical relationship. Both types of causation can exist, but they differ in their manifestation. Scientists use various methods to determine causation between states, but proving it can be challenging and requires multiple studies and evidence. Causation between states is crucial in scientific research as it allows for understanding relationships between variables and can help identify potential interventions and treatments.

In the use of the word "causation" can one say that one quantum state "causes" another if the two states are not measured? Or does the concept of causation only refer to a relationship between measurements?

A quantum state at time t=0 can evolve into a different state at t=T. In that case the first state clearly "caused" the second state.

OK, thanks, mfb
 

1. What is the difference between causation between states and causation between measurements?

Causation between states refers to a relationship between two variables or phenomena where one event or state directly influences the occurrence of another event or state. Causation between measurements, on the other hand, refers to a relationship between two measured variables where changes in one variable can be used to predict changes in the other variable. In other words, causation between states is a direct cause-and-effect relationship, while causation between measurements is a statistical relationship.

2. Can causation only exist between states or can it also exist between measurements?

Causation can exist between both states and measurements. However, the type of causation may differ. As mentioned before, causation between states is a direct cause-and-effect relationship, while causation between measurements is a statistical relationship. Therefore, causation can exist between both, but it may manifest in different ways.

3. How do scientists determine causation between states?

Scientists use various methods to determine causation between states, including experimental studies, observational studies, and statistical analyses. These methods allow scientists to control for other variables and establish a cause-and-effect relationship between two variables or phenomena.

4. Can causation between states be proven?

Proving causation between states can be challenging and often requires multiple studies and evidence from various sources. Scientists strive to establish a strong correlation between two variables, control for other factors, and rule out alternative explanations to provide evidence for causation between states. However, it is important to note that causation can never be proven with 100% certainty.

5. How does causation between states impact scientific research?

Causation between states is a fundamental concept in scientific research as it allows scientists to understand the relationships between different variables and phenomena. By establishing cause-and-effect relationships, scientists can make predictions and develop hypotheses that can be further tested and refined. Causation between states also helps in identifying potential interventions and treatments for various issues and problems.
