This isn’t to dispute serif vs sans-serif. I’m pointing the letter spacing. Doesn’t matter if it’s serif or sans-serif. If the fitting is bad, it’s going to be difficult to read. The vision system recognizes word shapes and it’s sensitive to how much space is between letters (kerning is a bit different, usually pairs of glyphs). Orthogonally, can you cite the scientific source that claims sans serif is better on displays? Curious when it was published. I wonder if it still applies to retina displays and hidpi screens.
