So step back from the vaccination debate and look at overall decision making. We all heuristics ("gut feeling") to make decisions. (wikipedia - simple, efficient rules which people often use to form judgments and make decisions). The problem is that heuristics are mental shortcuts and we focus on one aspect of a complex problem and ignore others. THis is fantastic for the highly skilled (bear with me) - with years of experience. E.g. a car mechanic who's spent years listening to cars, just "knows" the engine sounds dodgy.
However, it's not so useful for assessing information. You get what is called "cognitive bias" - again from Wikipedia - affecting choices in situations like valuing a house or deciding the outcome of a legal case. Heuristics usually govern automatic, intuitive judgments but can also be used as deliberate mental strategies when working from limited information.
A specific application is the "availability heuristic" - In psychology, availability is the ease with which a particular idea can be brought to mind. When people estimate how likely or how frequent an event is on the basis of its availability, they are using the availability heuristic.[6] When an infrequent event can be brought easily and vividly to mind, this heuristic overestimates its likelihood. For example, people overestimate their likelihood of dying in a dramatic event such as a tornado or terrorism. This heuristic is one of the reasons why people are more easily swayed by a single, vivid story than by a large body of statistical evidence.
Then there is confirmation bias.
Nate Silver has written about this regarding the US election. Right wing pundits refused to admit polls showed Obama would win.
So have a look at the actual stats on vaccination rates; outcomes and epidemology from the BIG data sets (with hundreds of thousands; millions of MMR vaccinations). Or, cherry pick data.
I doubt there is anything that would sway some of you of the merits of vaccination. BUT I've seen people devatasted by these preventable disesases (deaths and disability) and yet to meet a single person who's been affected by vaccination.
The MMR is the best available protection at the moment. That may change, but it's been used for close to 40 years in the UK - where are the millions of adverse outcomes?
