Peer reviews.. My work gets reviewed by fellow medics. My wife gets a double whammy of medics and pharmacists and other "toppest scientists" to use her "vernacular"
But Meadows was "peer reviewed". A lot of women ended up falsely imprisoned because of his "expert opinions"
Fortunately.. this has led the courts to exercise caution as a result of the miscarriages of justice.
But let's look further back and we are still endangering health because of .. Wakefield .. who leapt to the conclusion that because the measle virus was found in the gut of children suffering from the condiiton of autism that the vaccine was to blame. Not so. Later research found this unfounded.. yet Wakefield passed peer reviews at the time and this has done a
hell of a lot of damage as parents were exposed to Waily and Grauniad blasts which linger on into memories and folklore is then born.
All our kittens have had the required vaccinations.. including MMR. We foster one currently with aspergers. He did not have MMR as a baby. There were reasons to give him "singles" per the history. I am not naming this child so I am not giving away data

Merely pointing out his condition cannot be linked to MMR
How does this relate to PEER REVIEW
Walker's research.
He is exploring why so many autistic/aspergic kids seem to have a chronic bowel disease. Lot of lurgies in the gut .. and any one can be the cause. No one can prove the vaccine to be the cause and to simply publish the virus exists in the gut of autistic kids simply means the virus is present.. but not necessarily causing this condition.
Likewise the cam may record the speed but not prove the speed caused the accident
We look for causes. At the moment we are looking to cure the bowel discomfort lurgy within autistic sufferers as this will help them forwards.
We do not actually know which lurgy is to blame. We all have them by the way.. only some of us fight 'em off better
We have not really examined causes behind incidents or even set about curing it . None of it has been properly assessed or evaluated.
We only know if we train properly.. try to address attitude.. polite courteous manners.. COAST values - we might get a bit further on the road safety problem
