What was not said explicitly in the article is that all these virtues while needed in trying to understand (and find out, cut-through "bullshit") one has to hold of emotions and value judgements. And that is mighty difficult (things that we intuitively feel like should be or ought to be true). This is what B. Russell articulated so well in several of his maxims as well: "..the will to find out has to be much greater than the will to believe".
As a parting remark, one can observes the exact opposite is (implicitly) demanded from researchers, and vanishingly small number of people are able to stand their ground against the current of modern scientism (which infested normal discourse, education institutions, and even research). "Selling" yourself, selling results, being vocal, advertise, publishing for sake of publishing, those things are part of a metric these days. What to do when adhering to the real virtues touched upon in this writing will essentially kill ones career?
