I choose 1 time from a 8 items menu:
a + b log2 8 = a + 3b
I choose 2 times from a 4 items menu:
2(a + b log2 4) = 2a + 4b
a + 3b < 2a + 4b

In other words...information overload & paradox of choice
are more a quality issue (how options
are presented) than a quantity issue (n. of information)

1. Split

2. Customize

3. Info scent

Let’s recap
![Page 27: How to design interfaces for choice](https://reader033.vdocuments.us/reader033/viewer/2022051107/53eff8908d7f72a64f8b45b1/html5/thumbnails/27.jpg)
the paradox of choice is linked to the
consistency issue of a classification
wide structures work better than deep ones – but if and only if consistency is on
otherwise split, customize or provide information scent

This work is the prosecution of a research conducted with Andrea Resmini, published in some papers and merged in the book Pervasive Information Architecture.
