It is suggested that Jane and Rob may freely attempt any experiments as 'homework' to train abilities.

Training study: approximately 240 participants are randomly divided into three groups: self-exploration, standardized practice, and an active control with matched time; lasting 8 weeks with a 1-month follow-up; use novel objects and independently secured owner information; participants, on-site experimenters, and raters are blind to target identity; primary endpoint is pre-registered four-alternative forced-choice matching accuracy. Supplementary question 1: recruit an additional approximately 160 participants for two within-subject experiments, cross-manipulating normal light / low light / eyes closed, and prior visual hand position consistent / inconsistent with actual hand position; measure hand presence, ownership, and localization error. The eyes-closed condition creates residual conflict through visual adaptation before closing. Participants can perceive light conditions, so complete double-blinding cannot be claimed; blinding can be applied to specific hypotheses, hidden hand manipulations, and data analysis.

Exploratory Practice and Blinded Object–Biography Matching: A Pre-registered Randomized Trial

Only if post-training recognition of novel hidden information stably exceeds chance levels would this challenge the assumption that, excluding sensory input and prior knowledge, practice cannot increase information about randomly hidden targets.

'Any experiment can train' does not specify training dose, skill, or success criteria; specificity is low; one must first define which ability should improve to form a discriminating prediction.

The term 'untested' in the full text indicates that no study directly testing this specific proposition was found in this search, which does not prove that it has never been attempted historically; DOIs have been confirmed through publisher or PubMed records, but not re-checked via Crossref API; the sample sizes below are planned magnitudes; formal implementation must simulate power according to minimum effect of interest and clustering structure.
