Happy were the days when righteous Hollywood heroes persisted in their search for the truth despite all obstacles and deterrents.

The reality is, of course, very different. We live in the post-truth era, where (true) information is declining in value and belief is everything!

The bizarre thing is that we have more data than ever before, yet less facts can be deducted from it with certainty. Why is this? Let’s start with the economy, where data has been long used to find the best solution to anything and investment. Economic data despite its abundance holds any answer someone searches for. Algorithms dictate the value of stocks, prices and futures. They change in milliseconds and interact with one another – they are connected. People cannot keep up with the speed of machines and have no way of understanding what triggers events in machine agents. People then resort to plausibility, trust and beliefs (such as brand value). Companies can no longer be valued in real worth or assets, only in virtual billions that could be halved the next day.

News is another information channel that has become unreliable as a source in the search for facts and “truth”. News media are profit making organisations that feed on popularity not on truthfulness. What’s popular doesn’t have to be true. Any scandal is better than the truth. News media love Trump because he provides them with popular stories. Trump loves the media because they give him publicity and he doesn’t have to admit to anything they write about him, no matter how scandalous. Post-truth holds no proof. Even if the Intelligence Service would publish the Russian link to the election hack – it could be easily refuted as fake news or dark plot against him. Secret services are not employed to serve the truth, but to serve the enacted politics of the government (and their own interests). The electorate knows this. People only believe what they want to hear to confirm their beliefs!

Even in criminal courts finding an objective truth isn’t as easy as one would expect with all the forensic tools now available. Why else would we find this proliferation of criminal and terrorist activities with comparatively little or no convictions for lack of proof? Risks for criminals or extremists of getting caught and convicted are minimal – which itself sounds contradictory to the age of Big Data, ubiquitous surveillance, and integrated systems.

Far from finding an objective truth, even subjective truths are an endangered species. In a post-truth society an almost religious belief in perceived realities has developed that finds confirmation and amplification wherever data is abundant and where sources are better connected. Proof can no longer be provided.
