HUISWERK: Het vonnis in de Amerikaanse thimerosal-autisme rechtzaak
Citizen in Action en Belfort-group coördinator Gerry Nelissen schreef in zijn artikeltje Negen redenen om je niet tegen de Mexicaanse griep in te laten enten het volgende: “het Mexicaansegriepvaccin in flacons van tien doses bevat kwik (thiomersal) als bewaarmiddel. Thiomersal wordt ervan verdacht aan de basis te liggen van gevallen van autisme.” Vorige week besliste een speciale rechtbank in de US echter (voor de zoveelste keer) dat een verband tussen Thimerosal en autisme absoluut niet bewezen is.
De drie afzonderlijke beslissingen van de speciale rechters (12 maart 2010) zijn uiterst nuttige en leerrijke documenten geworden, en we hadden dan ook verwacht dat de Belfort-group deze teksten aan een grondig onderzoek ging onderwerpen, of alvast in de eerste plaats haar bezorgde achterban omtrent dit vonnis ging informeren. Op de websites van de Belfort-group, alsook op de websites van hun ‘alternatieve media’ partners, blijft het echter oorverdovend stil over deze belangrijke evolutie in de Thimerosal controverse.
Het bewijst eens te meer dat groeperingen als de Belfort-group uiteindelijk helemaal niet geïnteresseerd zijn in de wetenschap achter hun schadelijke claims, laat staan in het beschikbaar maken van informatie die hun samenzweerderige theorieën mogelijks onderuit haalt. Deze mensen gaan a priori uit van hun grote gelijk, en belichten de materie waarmee ze bezig zijn dan ook uiterst eenzijdig. Het had nochtans een goede gelegenheid kunnen zijn om de “integriteit” die de Belfort-group zo hoog in het vaandel draagt eens wat meer eer aan te doen. Of zoals de blogger op Vaccines Are Safe And Effective het uitdrukt:
The March 12, 2010 decisions of the vaccine court present those who believe that thimerosal caused autism with a huge test of their courage and morality. Are they willing to sit down and spend the time necessary to work through at least one of the vaccine court decision rejecting the existence of a link between thimerosal and autism? Because the decisions are not that difficult to read and they go through argument after argument raised by those who blamed the thimerosal in vaccines and explain why they are rejected. It will be very hard for the true believers to read these decisions, but if you are the parent of an autistic child and the child is undergoing treatment because of a concern with the thimerosal in vaccines, you owe your child the mental pain (no joke) of slowly but surely working through the decisions.

Vroeger kon men ook “wetenschappelijk bewijzen” dat roken niet schadelijk was voor de gezondheid. En dit werd toen ook door veel mensen aangenomen. Deze technieken worden nog steeds toegepast door wetenschappers die werken voor bepaalde multinationals….(bv. monsanto) Dus geloof niet alles wat wetenschappelijk bewezen is….

Beste Dirk,
Uw voorbeeld toont eigenlijk precies de kracht aan van de wetenschappelijke methode: na voldoende tijd en herhaald onderzoek worden de valse beweringen eruit gefilterd. Men moet altijd opletten voor de zogenaamde ‘confirmation bias’ (waar u impliciet naar verwijst): de menselijke neiging om enkel de ‘hits’ voor hun geliefde hypothese te tellen waardoor men blind wordt voor de belangrijke ‘misses’. En waar men al zeker voor moet opletten, is om de ‘misses’ weg te redeneren door hun hypothesen wat bij te stellen en/of allerlei ad-hoc hypothesen in te voeren. Moest de Belfort-group zich daar nu ook eens bewust van worden, dan zou een website als deze wellicht niet nodig zijn.
Met vriendelijke groet,

De Belfort-group is de mug die de wetenschapper wakker probeert te houden, die na een geleverde prestatie zijn geld aan het tellen is.
