The scientific method can only validate the scientific method. Things which fall outside of it it cannot handle.

Lets say ghosts are real. I'm not saying they are but lets say they are. They defy every test possible under scientific conditions and yet clearly exist. At that point you need to find a way to prove with science that ghosts exist, but any time you try to run a test they simply refuse to spawn and leave you high and dry.

It's a silly example but a valid one.

>>136841006
if you feel like reading their "argument"

It’s 2017, and people are still debating whether or not women are intellectually inferior to men, and whether we are entitled to a workplace that isn’t toxic to people simply based on their gender and sex. The Google employee memo about the apparent harms of diversity policies in Silicon Valley is both a shocking news story for the general public and for many women and gender minorities—especially of color—working in science, technology, engineering, mathematics, and medicine, a banal sign of normalcy.

At least science is helping us make progress, right? Science is sold to us as an almost holy, objective pursuit: a pure endeavor, a way of pursuing truth and only truth. As a high school senior planning to study physics and astronomy in college, I was thoroughly convinced that solving quantum gravity would trickle down to improved human relations. Of course, I was adorably naïve about both the difficulty that quantum gravity presented us (we’ve made little progress in the 18 years since I started university) and about the relationship between science and humanity’s various imperfections.

My education as a scientist did little to disabuse me of this simple view of science as a great unifier, as an objective means of distilling information. When skeptical members of my family argued that physics was dangerous because of nuclear weapons, I pointed out that it wasn’t science that was the problem but rather how people used it. But nowhere is it more evident that this perspective is flawed than when we consider the uses and abuses of evolutionary biology and its sibling, evolutionary psychology.

>>136848522
It is impossible to consider this field of science without grappling with the flaws of the institution—and of the deification—of science itself. For example: It was argued to me this week that the Google memo failed to constitute hostile behavior because it cited peer-reviewed articles that suggest women have different brains. The well-known scientist who made this comment to me is both a woman and someone who knows quite well that “peer-reviewed” and “correct” are not interchangeable terms. This brings us to the question that many have grappled with this week. It’s 2017, and to some extent scientific literature still supports a patriarchal view that ranks a man’s intellect above a woman’s.

It’s easy to end up in an endless loop of using our prodigious scientific skills to carefully debunk the shoddy science that props up this argument. This is important and valuable work, but it’s also worth considering why this loop exists at all. Science’s greatest myth is that it doesn’t encode bias and is always self-correcting. In fact, science has often made its living from encoding and justifying bias, and refusing to do anything about the fact that the data says something’s wrong.

>>136848586
Most saliently in the context of the Google memo, our scientific educations almost never talk about the invention of whiteness and the invention of race in tandem with the early scientific method which placed a high value on taxonomies—which unsurprisingly and almost certainly not coincidentally supported prevailing social views. The standard history of science that is taught to budding scientists is that during the Enlightenment, Europe went from the dark ages to, well, being enlightened by a more progressive mindset characterized by objective “science.” It is the rare scientific education that includes a simultaneous conversation about the rise of violent, imperialist globalization during the same time period. Very few curricula acknowledge that some European scientific “discoveries” were in fact collations of borrowed indigenous knowledge. And far too many universally call technology progress while failing to acknowledge that it has left us in a dangerously warmed climate.

Much of the science that resulted from this system, conducted primarily by white men, is what helped teach us that women were the inferior sex. Racial taxonomies conveniently confirmed that enslaving African people was a perfectly reasonable behavior since, as Thomas Jefferson put it, black people were “inferior to the whites in the endowments of body and mind.” Of course, this apparent inferiority never stopped Jefferson from repeatedly raping his wife’s half-sister, Sally Hemings, herself a product of rape. Jefferson is remembered as a great thinker, but when one reads his writing about race, it becomes immediately evident that rather than being much of a scientist, he was a biased white supremacist who hid behind science as a shield.

>>136844586
Unless they cite a study, then it is an undeniable fact.

>>136848669
The problem is that science was just the shield he needed in the 18th century, and unfortunately, it seems that it continues to function that way today. In other words, pseudoscience has always been a core feature of post-Enlightenment scientific knowledge and it remains that way because scientists refuse to integrate contemporary science, technology, and society studies research into university curricula. And so too many of us get out of school and end up in a world where we are suddenly forced to grapple with the reality of how science, in practice, is not as objective as we hoped. Enough of us have heard a man, sometimes the president of our college, sometimes our research adviser, express the view that women’s brains “just work differently” and “aren’t suited to technical skills” the way men’s are. Nonbinary people don’t exist, and transgender people are de-normalized in these narratives. Women of color listen to white women normalize Europe as the birthplace of scientific intelligence while telling us that our curly hair isn’t professional-looking. Senior men who we would hope could be mentors turn out to be our sexual harassers, and with some frequency, senior women tell us to suck it up and lean in, rather than helping us.

Last month, a study of women in astronomy and planetary science led by University of Illinois at Urbana–Champaign professor Kathryn Clancy found that women of color especially suffer from hostile working environments. In June, I contributed to a Nature Astronomy feature on gender discrimination in astronomy. As someone on Twitter reminded me last week when I posted a new paper on particle physics, because the authors of the paper are women, based on the results of one featured study in that Nature Astronomy issue, we can expect 10 percent fewer citations.

>>136846056
No but his point is that Science, on both sides, shouldn't be taken as a kind of religion.

Science as a collection of findings gets a lot of flak for switching position but that's its biggest strength: when something is proven wrong, it can change. Compared to religious or political orders, Science is absolutely something that can be looked at as objective and willing to change.

I'll say this, as a Physicist by education: while it is important to understand Science as a adapting truth, it is also important to make decisions based on what is understood to be most likely at that moment.

A typical scientific papoer (like the ones I wrote) has a "conclusions" section, with typical statement like: "based on this data we found, this is what we think is the most probable conclusion". But most leftists have never wrote or read a real scientific paper. thye think a guardian article is a scientific paper.

Google bro would argue that we ought to consider the possibility that white women and racial minorities simply produce lower-quality work, which is why we struggle to be recognized as competent knowledge producers. It’s time to turn the tables on this debate. Rather than leaning in and trying endlessly to prove our humanity and value, people like him should have to prove that our inferiority is the problem. Eliminate structural biases in education, health care, housing, and salaries that favor white men and see if we fail. Run the experiment. Be a scientist about it.

Well, it is not necessarily anti-fact, but it is explicitly anti-truth. They literally do not believe that truth exists, therefore it is pointless to look for it. Or worse, sometimes it is even damaging, since that which is claimed to be true is usually only rationalizing an oppressor narrative.

Worse even, they do not believe in dialectic or debate. They think that the only reason to ever have a conversation is to express power binaries in which one partner is the oppressed, and the other the oppressor. So when people think they're marshaling their evidence, preparing reasoned arguments, using sound logic, anticipating counterarguments and preparing to rebut them, what they're actually doing (according to the postmodernist) is oppressing their partner, who validates their oppression by listening.

So you see, they aren't concerned with facts. Only with narratives. And those narratives are binaries, usually power binaries. Can a fact exist? Sure, maybe. But just to talk about it changes it from a fact to a narrative.

>>136848345
>They defy every test possible under scientific conditions and yet clearly exist.
No. Then they don't exist.

>>136848345

>>136853000
We're talking the scientific method here, something that can be measured, tested and retested. These ghosts control their own physics, they fuck up your results so any result you get is invalid.

We also cannot test for consciousness as explained above you. There is no way you can test if something is conscious like you are. Something that wasn't conscious and yet was programmed to say it was would appear conscious to you when it actually isn't. This is the Turing test.

>>136848345
>At that point you need to find a way to prove with science that ghosts exist
Science is about proving theories wrong not right. The theories that survive are taken to be true because we haven't been able to prove them wrong. That and we can make technology based on those theories.

Attempts to verify claims of supernatural activity are often discovered to be hoaxes.

The natural is pretty super we don't need to make stuff up.

They don't like anything that does not agree with their agenda. This is what happens when you abandon religion and replace it with an incomplete ideology. Jordan Peterson has explained this multiple times. The leftists will use science when it suits them and reject it when it does not agree to their ideology.

The leftists may have all the facts in the world but they lack wisdom and this will be their undoing. They will attempt to censor the world to force people but the more you apply external force the more chaotic the system will become. Mark Passio covers it in his lecture on natural law. Spend the eight hours and give it a listen.

This is actually a real scientific problem we have at the moment. Observing something changes it's behaviour, there are particles that change behaviour purely based on being viewed. How do we test for natural behaviour if the fact that we observe it changes that behaviour?

It's literally an impossible problem because any way we interact with it, no matter how slight means that it gives us different results to if we interact with it.

So of course it's a strawman, it's totally made up because it was scaled up to be something silly.

Censorship and bullying tactics, until they start losing support, and decide to double down on the censorship, until they isolate themselves further and further into their own bubble of elitism which society eventually turns away from, and sooner or later, the bubble pops.

It's just a matter of what bubble will pop first - modern liberalism, the EU, or North Korea.

>>136859439
>How do we test for natural behaviour if the fact that we observe it changes that behaviour?

News sources are posting the memo without the references and graphs. We must spread the original version with all the citations included to help people find the truth.

who cares what they think, everyone should just laugh at them for the joke they are.

Lol, I agree with both statements. But Evolutionary Psychology is almost like a strawman for the authors point.

SETTLED SCIENCE

>>136841006

They trot out how much they support science when it serves them, and ignore it or worse when it doesn't.

Evolutionary Psychology is a field they've been trying to bury since its inception because its very existence undermines they're central ideology about human equality.

A real shame, because evopsych is one of the more falsifiable specializations. Their work lends a lot of credibility to the rest of psychology.

Reyc don't real madrid!

It's almost as if neither side cares about science for truth's sake and only wants to use it as an ideological bat to hit others with.

I read this article, went and archived so I could make a post about it here. Was pleasantly surprised to see it on the very top of the catalog. The author at the end challenges us, whoever that be, to eliminate structural biases in education, healthcare etc. i.e. blind enrollment or application processes. I think she'd be surprised to see these institutions would then be a lot less "diverse" and a lot more efficient without retarded neomarxists like herself running them. What annoys me is how liberals claim to be the bastions of science and facts, yet remain to be the only people so blind as to write an article like this. She truly is inferior if she believes 12% of what she says.

Can you imagine the pain of having to sit through that nonsense, and being called a bigot for even the most innocuous cross examination?

Because it destroys their narrative and reduces any sort of power they have.

>>136841006
They are of course referring to "Belief in Science", not the scientific method. For them, Science is a subsumable adjacent religion with some problematic dogma that needs to be eliminated in their syncretic process.

They really think they'll be able to sell machine intelligence on the idea that niggers are humans and gender is a spectrum.
