Causal inference is more difficult in quasi-experimental designs because they lack random assignment to conditions, which is a crucial element for establishing causality. Without random assignment, it is possible that pre-existing differences between groups (such as differences in personality or motivation) could be responsible for any observed differences in outcomes, rather than the experimental manipulation being studied.
