Vaccinations - good or bad


Vaccines are here. At first, and with their inventor Pasteur, vaccines were suspect. Then they were accepted. By 1855, the first required vaccines for school children were instituted in Massachusetts. They had a good run, with public trust almost complete.  Then came the first problem with a vaccine that couldn’t track a tricky disease, influenza. Then came a correlation of a vaccine with a worse condition, autism.  Now vaccines again are suspect once again.
  
Case A. We see a decline in flu cases as the use of flu vaccines increase.  Too complicated for many is this simple relation. They see only the first part, the “decline in flu cases,” and so getting the flu vaccine is unnecessary and always inconvenient. So, they don’t. So, more flu cases occur. This initiates a cycle via this simple rule: Fewer flu cases this year implies fewer flu shots next year implies more flu cases. Surprised?

Case B. In another situation, recall the 1998 (false) report that the MMR (Measles-mumps-rubella) vaccine causes autism.  Many “enlightened” parents then declined to have their children so vaccinated. Even after the report was summarily debunked, some parents still continued to deny MMR for their kids. The result was an increase in these diseases in children. 

In the first case we have a false feedback logic and in the second, uninformed reasoning. One problem is that statistical evidence is never 100%.  Give injections of purified water to twenty million and some side effects will occur, statistically insignificant to be sure, but some will read causation in there.  

Currently, required vaccinations for children are true saviors of our very lives:
Diphtheria-tetanus-acellular pertussis (DTaP)
Inactivated polio vaccine (IPV)
Measles-mumps-rubella (MMR)
Varicella (chickenpox)
Haemophilus influenzae type b (Hib)
Pneumococcal conjugate (PCV13)
Hepatitis B (Hep B)
We would be in deep, really deep, trouble if these vaccines required annual booster shots.

The Pros and Cons of vaccinations are well studied.  At the website https://vaccines.procon.org/, you can find a balanced and reasonable set of both. For example, on the pro side, vaccinations have a huge multiplier effect in costs saved and earned.  Money is always big!  As well, general health is strongly supported by vaccinations. However, each pro and each con consumes a full paragraph of information.  Multiply each by ten, and “everyman” becomes overloaded.  What is important these days is that many people will select just one of these and magnify it to become the one and only pro or con, forgetting the others.

Vaccines are not only here, they are here to stay.

BTW. If you have a vaccination preference, you may be called a “vaxxer” or “antivaxxer.”

Accepting Fake Information

Every day, we are all bombarded with information, especially on news channels.  One group claims it's false; another calls it the truth. How can we know when to accept it or alternatively how can we know it's false? There are several factors which influence acceptance of fake or false information. Here are the big four.  Some just don’t have the knowledge to discern fact/truth from fiction/fact/false*. Some fake information is cleverly disguised and simply appears to be correct. Some fake information is accepted because the person wants to believe it. Some fake information is accepted because there is no other information to the contrary. However, the acceptance of  information  of any kind become a kind of  truth , and this is a well studied topic. In the link below is an essay on “The Truth About Truth.” This shows simply that what is your point of view, different types of information are generally accepted, fake or not.   https://www.linkedin.com/posts/g-donald-allen-420b03

Your Brain Within Your Brain

  Your Bicameral Brain by Don Allen Have you ever gone to another room to get something, but when you got there you forgot what you were after? Have you ever experienced a flash of insight, but when you went to look it up online, you couldn’t even remember the keyword? You think you forgot it completely. How can it happen so fast? You worry your memory is failing. Are you merely absent-minded? You try to be amused. But maybe you didn’t forget.   Just maybe that flash of insight, clear and present for an instant, was never given in the verbal form, but another type of intelligence you possess, that you use, and that communicates only to you. We are trained to live in a verbal world, where words matter most. Aside from emotions, we are unable to conjure up other, nonverbal, forms of intelligence we primitively, pre-verbally, possess but don’t know how to use. Alas, we live in a world of words, stewing in the alphabet, sleeping under pages of paragraphs, almost ignoring one of

Is Artificial Intelligence Conscious?

  Is Artificial Intelligence Conscious? I truly like the study of consciousness, though it is safe to say no one really knows what it is. Some philosophers has avoided the problem by claiming consciousness simply doesn’t exist. It's the ultimate escape clause. However, the "therefore, it does not exist" argument also applies to "truth", "God", and even "reality" all quite beyond a consensus description for at least three millennia. For each issue or problem defying description or understanding, simply escape the problem by claiming it doesn’t exist. Problem solved or problem avoided? Alternately, as Daniel Dennett explains consciousness as an account of the various calculations occurring in the brain at close to the same time. However, he goes on to say that consciousness is so insignificant, especially compared to our exalted notions of it, that it might as well not exist [1] . Oh, well. Getting back to consciousness, most of us have view
