Expert writing Tips
Best practice
When discussing research findings, explicitly state the "causal relation" being investigated to avoid ambiguity. For example, instead of saying 'There is a relation between A and B', say 'There is a causal relation between A and B, where A is hypothesized to cause B'.
Common error
Avoid assuming a "causal relation" solely based on observed correlation. Just because two events occur together does not mean one causes the other. Further evidence is required to establish causality.
