I think this is an extremely important piece of scientific work that explores an element I feel like I have encountered throughout my life. However I fear it will be ignored because the bias is too strong in our society. People simply cannot engage with the subject of “perception of moral decline might be an effect made up of psychological biases” without immediately going to their own backlog of evidence they have composed to support their own biased position.

And to the point of importance. This bias is a major component of the campaign for the previous president of America Donald J Trump, and is also used consistently throughout right-leaning political parties around the world. The notion that “things used to be better” is very strongly tied to the biased perceptions that “things have definitely gotten worse recently” but they might both be objectively wrong and people just displaying bias.
