Feel free,
@alex3619 , to elaborate, as this issue is crucial to all people, in an ever more urgent way.
This is my current interpretation of what is happening, but its far from complete and there will be lots of things I have not taken into account.
There is a congruence of factors, mostly originating in the 70s. The first is a political ideology, that meshes with an economic ideology, and sometimes called Thatcherism or Reagonism. Its basically that government has to be efficient as a priority over other concerns. Bureaucratic "evidence based" agencies follow from this idea, such as NICE, as do economic rationalist cutbacks to government services. Here money is the key thing, and actually providing the services government have a mandate to provide seem secondary.
Now normally the investigative media would expose these kinds of things. In the UK however the government can suppress stories. At the same time the rise of the internet damaged the economic model for news media, and in a true economic rationalist fashion they responded by firing the reporters they need for quality news. This was compensated for by a rise in churnalism, or repeating stories others investigated. Reporters not only had to cover more stories as a result of this, they had to do it on smaller budgets and with less time. Its no wonder the temptation to use stories investigated by others is so rife. Yet the more this happened the worse the coverage got, and the less people bothered to pay for news. Its a vicious cycle, and has seen many news media companies, especially newspapers, fail.
Large corporations have come to be more influential in recent times, and push for economic agendas that suit them, not the general public. This is compounded by the rise in public relations companies, and their covert posting on social media, which I see really started in the 60s with campaigns to counter antibusiness and environmental activism. In medical research and other areas this led to a rise in zombie science, which I blogged about a few years back. That is science supported by money (and for government by political support) rather than good results. This science is often bad, but it wont die so long as funding is maintained.
HOPE
Now while part of this is ideological, and has failed to produced promised results (economic rationalism) the rise of the internet has led to grass roots politics being organised on a larger scale. This means individuals can be engaged in politics in numbers that were never available before. It also led to the rise of crowdfunding. Corporations have the right to engage in activity I would call political, but so does the average person. Democracy will fail without good information and lots of people getting involved.
What I was expecting is the rise of independent journalism groups with subscription and crowdfunding as a way to fund deep investigations. What I currently see, and I have not been looking, is one example, in David Tuller, except he managed to do this within academic auspices. I had never considered that likely, but I guess its very viable now, for at least some journalists. It wont cover everyone as such positions are not great in number, and journalism needs to keep and develop seasoned investigators, who specialise in specific areas. Leave the food critics reporting on medical science to the cash strapped papers.
We also have organisations like the Science Media Centre which operates a lot like a public relations company, though via donors rather than fees. My counter to that was going to be public and charity funded information distribution sources, with fast and easy access to information to the media. When my health crashed five years ago all my blogging on this and biochemistry issues slowed to a crawl.
In medicine doctors have long held a view they should not be political. That has not stopped other forces meddling in medical politics. Hence we have the rise of doctors as agents of the state, and doctors who cannot practice medicine in the best interest of themselves and patients, but within government, agency or corporation guidelines. The issue here is that there are many things in which such guidelines are justified, but many more are about delivering cheaper services, not better services. If doctors start to get more political, though perhaps only in medical matters, they might be able to counter those trends. I think many of the public would support them.
