There's a bunch of comments in this thread from people who did not read even the abstract of the study.

Those 3 data points were used in a graphic, which is not relevant to the actual experiment performed. Their experiment focused on cohorts of "parents who were (just) entitled to the new paternity leave" and "(just) ineligible parents". This design provides quasi-randomization so that any prior "downward trend" is not relevant, and clearly there are more than "3 data points" at play.
