The study, conducted by former psychology student Natasha Bauer during last year's Rugby World Cup as part of her clinical psychology dissertation, involved watching the television coverage of all 48 games of the tournament.
Bauer noted the commentators tended to downplay the possible effects of head knocks on players by describing such incidents through jokes and colloquial expressions.
How often do you hear commentators refer to a player wobbling around "like a drunken rhino" and being "knocked for six" or, in an allusion to the symptoms following an on-field clash, "wonder how many sets of goal posts he's looking at now?" while their sidekicks chuckle along?
Those tired cliches have become just as outdated in their sentiment.
Then there are the television segments like Smashed'Em Bro, which, with the assistance of slow-motion replay, celebrate brutality.
There's nothing wrong with celebrating a great tackle, but there is something a little bit sadistic in applauding a hit that injures.
It's the old watching-motorsport-to-see-the-crashes syndrome; ferocious hits are an integral part of the entertainment package.
Leaving it all out on the field is what we expect of our footy stars. Perhaps we need to tweak our attitude slightly to "leave it all out on the field fellas, except your brain cells".
Too often we see professional rugby and league players receive a blow to the head, stumble around a bit, get a drink of water from the trainer, shake it off and carry on.
When kids see their heroes playing on when they are obviously affected by a head knock, they think they're being courageous; what they need to think is that they're being stupid.
There is no way children are going to stop playing contact sports, nor should they - the rough and tumble of games is an important part of being a kid.
Contact sport is here to stay, but our attitude towards head/brain injuries needs to change.
Everyone with a stake in these sports, from the games' marketers to media to fans, has a role to play in reinforcing the point that concussion is no laughing matter.
