If we take the premise that income is the single most important factor correlated with happiness, then I think the acceleration effects do seem to imply that there is no happiness ceiling. However, I’m not sure how reasonable this premise is in the first place. I suspect we’re zooming in on a well studied effect and if we zoom out a bit, there are many plausible hypotheses for why acceleration effects does not rule out a happiness ceiling, namely that other factors impact the high end of the scale more.
I notice this being muddied in the references to the happiness ceiling. On one hand, the happiness ceiling is only being defined or evaluated in the income sense, and on the other, the conclusions are described as though the income-happiness-ceiling is the only effect and therefore equivalent to all possible models of the happiness ceiling.
A separate question: how does the mathematical relationship relate in practice, e.g. if I have 9⁄10 happiness, then 10x my income, then am “only” 10⁄10 happy because I can’t exceed 10? I haven’t seen this explained before, and I have some concerns about whether it’s valid to draw conclusions about this part of the curve without more complicated design. (In other words, I think the extreme end of the scale is an exception and that different study design is required to understand it more objectively.)
