Honest about what brain training is
The brain-training industry has a credibility problem, and it earned it. We'd rather be straight with you about what CogDojo is, what it measures, and — just as importantly — what it doesn't do. This page is the line we hold ourselves to.
What CogDojo actually is
CogDojo is a measurement and habit tool. It takes short, daily cognitive games and turns your practice into numbers you can see: a rating per skill, a single Brain Fitness Index, and a comparison against your own age group. The point is to make consistent practice engaging and your progress visible. That's a genuinely useful thing — and it's a modest, honest claim we can stand behind.
What we claim
Measure your performance on CogDojo's games, consistently over time.
Give every cognitive skill its own rating and a readable trend line.
Roll those ratings into one Brain Fitness Index you can watch move.
Show how your scores compare to others in your own age bracket.
Keep practice short, adaptive, and engaging so the habit sticks.
What we don't
Claim CogDojo makes you smarter at work, school, sport, or driving.
Claim it prevents, delays, or treats cognitive decline or dementia.
Present it as a medical device or a substitute for professional care.
Imply that a rising Brain Fitness Index reflects real-world ability.
Use testimonials to stand in for evidence we don't have.
On whether brain training “works”
The research is honestly mixed. There's reasonable evidence that you get better at the specific tasks you practise — practice effects are real. The harder question is whether that improvement transfers to unrelated, everyday abilities, and on that the scientific consensus is far from settled. Studies point in different directions, and large reviews have urged caution about broad claims.
We won't paper over that. So we frame CogDojo around what we can actually demonstrate — that it measures your performance on our games over time and gives you a reason to keep practising — rather than around outcomes we can't responsibly promise.
Over-claiming isn't just dishonest — it's been penalised
In 2016, a major brain-training company was fined two million dollars by the U.S. Federal Trade Commission for advertising that its games improved real-world performance and staved off age-related decline — claims regulators found weren't backed by reliable scientific evidence. We took the lesson to heart. Hedged, honest language isn't a legal hoop we grudgingly jump through; it's the brand. If a claim can't be substantiated, we don't make it.
