An example LNS search that is easier than an LS search. The LNS search for a 0° target among 20° and −40° (A) is easier than an LS search for 20° among 0° and −40° (E). The related simple searches show that although the LNS target is slightly more similar to one of the distracters compared to LNS (0° among 20° is harder than 20° among 0°; B vs. F), the other distracter is less similar for LNS over LS (0° among −40° is easier than 20° among −40°; C vs. G), and the two distracters in LNS are more similar than the two distracters in LS (20° among −40° is harder than 0° among −40°; D vs. H). Thus, the LNS search has a target that is less similar to its distracters and has more homogeneous distracters, making it easier than the LS search.
