Does Sheldrake's animal telepathy research demonstrate interspecies psi?

The Jaytee controversy is unique in parapsychology: two research teams filmed the same dog during overlapping periods and reached opposite conclusions. Sheldrake's program began with a 9-month observational study (1998) showing a highly significant correlation between Jaytee's window-sitting and the owner's departure time (F=43.3, p<0.0001); the 2000 videotaped follow-up extended this. Wiseman used a pass/fail threshold (>50% time at window) and found no significant difference, while Sheldrake used a continuous proportion measure. Neither analysis is unambiguously correct, and the dispute turns on what counts as "anticipatory behavior." The Kane study (Sheldrake & Smart 2000) directly replicated the Jaytee protocol with a different dog and owner, finding similar effects (p=0.0002), addressing reproducibility concerns but with N=1. The N'kisi parrot study is methodologically more transparent (language-based scoring with blind transcribers) but has not been independently replicated, and reviewer Jeffrey Scargle raised an unresolved concern about cultural selection bias in the vocabulary–image pairing. The library now holds the full arc of the Jaytee pro-evidence (1998 preliminary + 2000 Kane replication + 2000 videotaped) alongside Wiseman, Smith & Milton (1998).
