Contrarian
Many people call themselves "free thinkers" but are actually contrarians who define most of their positions in opposition to a perceived enemy rather than their own reasoning or evidence.
"Inside every cynical person is a disappointed idealist." -George Carlin
Trolls are the classic contrarians, and their influence on social media and Internet culture has infected a significant amount of normal discourse. Atheists are contrarians when it comes to religion. And a lot of the right wing internet is contrarian because it exists as a critique of liberalism rather than the promotion of any positive alternate ideology. Leftist contrarians are known as "Tankies."
Understanding how much people's political positions pivot whenever a mistrusted institution makes a claim will make a lot of things make sense that don't when you look for a rational or ideological interpretation.
Contrarian Democracy
While references to contrarianism in this wiki do not refer to Peter Thiel's investment strategy, there is significant overlap between those who employ it as investors, libercontrarians who believe selfishness is altruism, the right-wing manosphere that thinks misogyny is sexy, propaganda and misinformation intended to deceive, and trolls who just do it to mess with people before eventually becoming the very thing they originally sought to mock. All of these groups share a fundamental mistrust in institutions and the liberal democratic world order, and reflexively reject any ideas they associate with it.
The result of this coalition of cooperating contrarians is that a platform based on the destruction of democratic institutions is able to gain majority support. If enacted, it will undo decades of social progress, and open the door to all kinds of corruption and calamity that those institutions were created to prevent. If the balance of power is significantly disrupted, it can create a feedback loop of authoritarian power consolidation that will be difficult to break.
Contrarian Public Health
Contrarianism is also having a huge impact on public health. The loss of trust isn't wholly unjustified, since there have been so many cases of FDA regulatory capture by the pharmaceutical industry, private health systems that prioritize profits over patients, and a media that puts ratings and sponsorships over consistent, evidence-based advice. However, that is really not a good reason to question vaccines, which are one of the few places that affordable one-time cures are actually produced. Expensive long-term treatments of the symptoms are much more profitable, and research priorities reflect this. Our healthcare system tends to overmedicate, but that doesn't mean you should ignore doctors while blindly accepting the advice of anyone who professes a skepticism of "western medicine." Sometimes the regulatory authorities say something is bullshit because it really is, not because they are in a conspiracy to suppress the herbal cure for cancer in order to maintain their profits.
Devil Advocacy
While playing the devil's advocate can be useful for examining the other side's perspective in a debate, it is common for contrarians to do it in a way that seems more like trolling, or just taking the devil's side. The one can become the other if not careful. Moderation in devil advocacy is recommended to avoid being annoying.
Extreme Contrarianism
The most devoted contrarians will look for the broadest possible consensus positions and take the opposite stance. Such extreme contrarianism was rare in the pre-Internet days when it was impossible to build any community around them. If you were a Flat Earther, you were probably the only one you'd ever know. The communities that form around extreme contrarian ideas use in-group dynamics to reinforce these beliefs that suggest the entire rest of the world has gotten it wrong.
Conspiracy theories are extreme contrarianism that has gone mainstream, with a significant percentage of conservatives expressing QAnon-based beliefs.
Creationism is a form of extreme contrarianism, where disagreeing with the scientific consensus on evolution makes you seem pious to your fellow fundamentalists.
Then you have pop-culture contrarians like Brian Griffin who just love to criticize anything that is widely liked.
The man in this song is taking the contrarian position that she will not be able to do those things better. A critical thinker would have responded "it depends" and evaluated their relative skill at each suggested task. The woman in this song is being overconfident, but not contrarian.
