You're objections are all fine, but post hoc as they are additional qualifiers that seem driven more by personal preferences than anything which can be used as a more objective criterion. You believe that I should be able to "connect the dots" in the same way that you do, but when there are so few dots, it's easy for one person to see Ursa Major, another a dipper, and a third a plow.
My entire point is that your data points are too vague and have multiple reasonable interpretations, and that it's possible to make it more rigorous.
You did not specify what "mythologize" means. I interpreted it mean "the subject of a biopic" produced by a movie studio for the big screen. You give a dictionary definition, but that doesn't define what it means to 'mythologize' someone in a movie, or determine if some group is excessively or under-mythologized. Is a biopic about Plato mythologizing Plato? Which groups do or don't need mythologization? Are British biopics over or under represented?
You believe that a movie about the Nobel Peace Prize winner Joseph Rotblat is likely about to "pass judgement on all the other guys who didn't leave the Manhattan Project" and not about the events that lead to his getting the Peace Prize. I have just watched the film, and it does not do what you pessimistically assumed.
You believe that a movie about research which is usually interpreted as a caution against the implicit acceptance of authoritarian roles, is actually about research about the "the horrible things this white guy did to people".
(You write about Milgram's 'inhumane experiments'. While he worked to understand why humans might do things that are inhumane, the people being "shocked" were actors. It was emotionally stressful, certainly, though as http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4346260/ comments, "Milgram invoked post-experimental survey data and psychiatrists’ reports to demonstrate that most participants were glad to have participated and that none had been harmed". It adds careful qualifiers to that interpretation. What part of his experiments do you consider to be 'inhumane'?)
And you don't like moves that are well-regarded by those in the social justice movement. Nor, if I understand your objection to "A Dangerous Method", is a film acceptable if it has a female actor on the movie poster, even though your original criteria asked about "the regular white guy scientists .. we've mythologized", and not movies which only mythologize regular white male scientists. This feels very might like raising the goal posts.
Again, this is acceptable. You get to define your own coding criteria, so long as it's transparent enough that others can have a hope of reproducing it.
It does mean that "Dr. Strangelove" (1964), which is about white men bringing nuclear destruction to the world, where one of the main characters is handicapped, and is well-loved by the anti-war crowd, is an example of movie that you think puts straight white males in a bad light. "A Clockwork Orange", "Brazil", and "1984" all portray white men in oppressive positions of power. As reactions to authoritarianism is the topic of Milgram's work, these also seem to fall into your pattern.
Again, perfectly acceptable. Once you define your criteria, it can be applied more rigorously against a longer period of time, to see if there's a trend.
Of course, it ends up with strange problems, where "Wrath of Khan", which has the Indian character Khan Noonien Singh (played by the Mexican actor Ricardo Montalbán) on the movie poster, so doesn't count as a white, straight, male movie. Ghostbusters II (1989) has a black man on the movie poster. Tony Stark in the "Iron Man" films has a chest injury which requires him to wear a regulator for his heart, so is handicapped. "Star Wars" (1977) also had a woman on the movie poster.
As "Dr. Strangelove" and these examples show, this "pattern" you've identified, of sometimes having non-white, non-male, non-straight, or handicapped actors, has been around for a long time. It's not clear that it's a new thing, and seems to match the secular trend since the 1960s of letting people besides white, straight men have the positions of power in US politics, science, and other fields.
You said "I was hoping you would notice from context I was referencing male scientists who were publicly disgraced as people, not as fraudulent scientists.", in regards to "publicly disgraced in the past year (offhand I can think of 3)".
I believe you are limiting the topic to people who have not been disgraced for scientific reasons but because of other events in their lives. That is, despite that some of the disgraced people I mentioned committed no crime, their social ostracism isn't the right kind of social ostracism for you. I presume the only criteria you accept is that the person must be criticized for racist, sexist, or similar reasons?
With that qualifier in mind, I assume you mean Watson, Taylor, and Hunt. Do note that Watson has been disgraced "as a person" for years for his racist and sexist views.
For example, in http://www.independent.co.uk/news/science/fury-at-dna-pionee... from 2007 titled "Fury at DNA pioneer's theory: Africans are less intelligent than Westerners" and subtitled "Celebrated scientist attacked for race comments: "All our social policies are based on the fact that their intelligence is the same as ours - whereas all the testing says not really". This caused people to, for example, cancel his visit (http://news.bbc.co.uk/2/hi/uk_news/england/london/7050020.st...) and "Because of the public controversy, on 18 October 2007, the Board of Trustees at Cold Spring Harbor Laboratory suspended Watson's administrative responsibilities." Indeed, the reason why he sold his Nobel Prize last year was to make money, because he had been ostracized for years, and wanted the money.
Thus, only two of those have happened this year, and not the three you suggested. Or are you thinking of someone else? If so, who?
Other similarly personally disgraced scientists include Kary Mullis, Nobel Prize winner and well known HIV/AIDS denialist, climate change denialist, and believer in astrology; and William Shockley, a Nobel Prize winner also known for his racist views and support for eugenics.
Of course there have been few women who have won the Nobel Prize, so with only 4 examples of male Nobel Prize winners ostracized for their views, we would not expect there to be a female winner similarly ostracized. Thus, lack of such a counter-examples is completely expected from the statistics.
Since you include astronauts as a field of science, it's easy to point to Lisa Nowak, who has been personally disgraced for her attempt at kidnapping Colleen Shipman, who pleaded guilty to charges of felony burglary of a car and misdemeanor battery, and who was discharged from the Navy in under other than honorable conditions. However, part of that was quite clearly illegal, so may not constitute the right kind of disgrace "as a person" that you are looking for.
But these are events that hit the big time news. What do you know about scientists who aren't Nobel Prize winners, and who aren't on world-wide TV?
That's why a more rigorous search is needed. Retraction Watch and Science magazine both use the phrase "disgraced" in reference to scientists, and have a more complete coverage of what goes on in science. Do note that those science oriented sites don't use "disgraced" to refer to the racism and sexism of Watson, et al., so the term "disgraced" is itself rather ill-defined.
For example, in http://news.sciencemag.org/people-events/2013/10/special-rep... a co-worker says of Anja Strømme “She feels abused and disgraced, and it should have never happened”; do we accept that this is a case of being disgraced? If not, what constitutes a sufficient level of disgrace?
Or, if many male scientists thought it was disgraceful that a woman like Lise Meitner should work in physics, and snubbed her socially and in her career, is that really disgraceful? Or do you require that someone be successful and famous first, before being disgraced?
If your definition is so strict that only a few people over the decades meet the definition, the it's hardly a useful definition, is it? Who else can you think of that have been disgraced? You make it sound like something that's happened more than a dozen times, so it shouldn't be hard to come up with more examples, no? Based on those numbers, how many women do you think should have been disgraced by this time?
