Why is the gravitational force difference between a supermoon and an apogee moon deemed insignificant for human mood?

Answer

The difference is extremely small relative to the Earth's overall gravitational field

The minor increase in tidal force experienced during a supermoon is minuscule when compared to the Earth's massive gravitational field, making it insufficient to directly alter human chemistry or mood.
