5 Blind-Sighted Continuum Blind-sighted measure –For all k variants: 0 ≤ r pq ≤ 1, where 0 = perfect blindness 1 = perfect sightedness –For subset of variants p i > 0, truncated r pq Special Case 1: r pq = 1, if all ps, us, and qs equiprobable Special Case 2: r pq = 0, if only all ps equiprobable

7 Sequential Selection Need to add a index for consecutive trials to allow for changes in the parameter values: p 1t, p 2t, p 3t,... p it,... p kt u 1t, u 2t, u 3t,... u it,... u kt q 1t, q 2t, q 3t,... q it,... q kt where t = 1, 2, 3,... n (number of trials) Then, 0 ≤ r pq (t) ≤ 1

8 Sequential Selection N.B.: Although r pq (t) → 1 as t → n, –it would not do so monotonically except under highly unlikely circumstances, –e.g., when ρ pu (t) = -1 (i.e., where the rank-order correlation between the ps and us is perfectly negative) –Hence, the problem of local utility maxima and the question of when to terminate BVSR

9 Three Final Points Although the above formulation is very abstract, it can be readily explicated in terms of concrete examples Moreover, by deriving the blind-sighted continuum, the formulation allows us to avoid useless debates about BVSR That said, it is likely that highly creative scientists often operate at the blind end of the continuum
