The 'fake' element is everywhere: in the news, in science, in high-tech, in relations between people, relations between countries etc...
The worst form of fake is within the family. Fake family members will pretend to care about you and love you, but they'll disappear when help is needed. There are many examples of parents and siblings left to struggle alone with their problems , especially health issues. It's very frustrating when one realizes that a trusted family member has been faking intentions towards you all along.
Fake science is called pseudoscience, and it consists of beliefs that claim to be scientific and factual, but are incompatible with the scientific method. For instance, health alternative therapies and remedies. I must admit, I don't care whether these methods are considered fake, as long as they help me, and some of them do help me.
Fake news are deliberately fabricated to deceive readers and spread misinformation for various reasons, mostly political, ideological ones; partly for business interests or for fun. We have them all the time, and they do society a lot of damage. During the last years, fake news travel fast via social platforms (Facebook, What's up, etc...).
There's, sadly, no compassion among people or countries. Relations are based mainly on Interest - interest in things that might offer mutual or one-sided advantage.
The approach of 'fake it until you make it' is sometimes seen in the Hightech industry - which is highly competitive. By pretending to have certain skills and projecting confidence, one believes it's possible to achieve a dream job.
It's a cruel world, and it's difficult to live real in a fake culture.
