Impact
BGLI publishes how it measures before it publishes what it found. Where cohort data does not exist yet, the method and the reporting date are stated instead of an estimate.
The instruments
A gradual-onset continuous performance task administered at intake, at close and at six months, run at the end of a working day rather than a rested morning. We report reaction-time variability, not only accuracy, because variability is what degrades first in senior operators.
Overnight and post-stressor RMSSD captured with a chest strap for the fortnight either side of a residency. The measure of interest is recovery slope after a controlled cognitive stressor, not resting baseline, which is confounded by fitness and altitude.
A validated exhaustion and disengagement inventory, self-reported, with the known ceiling effects stated in every report. Self-report is weak evidence on its own and is never presented without a behavioural measure alongside it.
Direct reports and one peer rate the quality of decisions they observed, blind to the participant's cohort timing. This is the measure that matters most to the institutions paying for the seat, and the hardest to run cleanly.
Reporting schedule
Q2 2027
First GMC cohort closes. Baseline and close data locked.
Q4 2027
First cohort report published in full, including instruments and dropouts.
Q2 2028
Six-month follow-up on cohorts one and two.
2029
First twelve-month decision-quality 360 across three cohorts.
Said plainly
No cohort has reached its twelve-month follow-up. Any figure quoted about BGLI outcomes today would be a projection dressed as a finding, so there are none on this site.
Attention training produces reliable, modest effects on sustained attention and stress recovery in working adults. Effects on organisational decision quality are far less established. BGLI's contribution is meant to be evidence at that second level.
Protocols are lodged before data collection with our research partners, and results are written up whether or not they support the programme. A measurement programme that only publishes wins is marketing.
