Attacks and scepticism are on the rise, even as leaps are made in fields from gene editing and AI to interplanetary exploration
The
2010s were the decade in which we were reminded that science is just a
method, like the rhythm method. And just like the rhythm method, it can
be more or less rigorously applied, sabotaged, overrated, underrated and
ignored. If you don’t treat it with respect, you may not get the
optimal result, but that’s not the method’s fault.
That may be where the similarities end, because when it’s done well, science is very effective, and this decade furnished its fair share of breakthroughs to make us gasp. Physicists detected phenomena that were predicted decades ago – gravitational waves, the Higgs boson particle – indicating that they have been on broadly the right track in their understanding of how the universe works. Astronomers added awe-inspiring detail. Nasa probes found towering ice mountains on Pluto and organic chemistry – the stuff of life – on Mars and a moon of Saturn. And who could forget the exoplanets – those planets orbiting distant stars? Thousands of them were discovered in just the past 10 years. No wonder science fiction is booming.
Biologists didn’t slack either. They honed an immunological defence mechanism found in bacteria, Crispr-Cas9, into a powerful gene-editing tool that works in plants and animals – including humans. They added several new ancestors to the human family tree – and discovered
ghostly traces of others as yet unseen and unnamed. And very old DNA
started giving up its secrets, after researchers succeeded in extracting
it from ancient bodily remains and sequencing it. This threw open a
huge window on our species’ past, revealing that every person alive
today is the product of multiple migrations and that relations between
different waves of migration have always been complicated. Neanderthals
and modern humans probably clobbered each other, for example, but they
also interbred.That may be where the similarities end, because when it’s done well, science is very effective, and this decade furnished its fair share of breakthroughs to make us gasp.

But this was also the decade in which science was commandeered by all kinds of people with political, social and economic axes to grind. Ancient DNA researchers understood early on the potential for their discoveries to be politicised – the science of human origins always has been – but they still weren’t able to fully control the message. Thus we learned about white supremacists engaging in sinister milk-chugging parties in America, supposedly designed to smoke out people of non-European heritage who can’t digest lactose, and baseless claims made by some Hindu nationalists that the speakers of the original Indo-European language hailed from the Indian subcontinent. Ancient DNA researchers themselves were accused of engaging in an undignified “bone rush”, and disrespecting indigenous remains.
Dissing the dead is one thing, dissing the living quite another. The world was shocked when, in 2018, the Chinese biophysicist He Jiankui announced he had used Crispr to edit the genomes of twin girls – the first humans born with edited DNA they can pass on. Ethical concerns were raised over who’s entitled to know what about private health records as genetic testing becomes mainstream, and over the prohibitive pricing of gene therapies after the first of these was approved in 2012 – then taken off the market.
We heard a lot in this decade about how trust in experts has waned, but it’s difficult to know how much of that perception is real and how much of it comes down to minority opinions bellowed through the sousaphone of social media. In 2019, the US-based organisation Scholars at Risk reported that attacks on higher education communities had more than doubled globally over the previous three years – ranging from restrictions on academic expression to wrongful imprisonment and even violence. On the other hand, surveys suggest that trust in scientists is quite stable over the long term, and science funding has been slowly increasing in the world’s richest countries.
Taken together, perhaps what these indicators reflect is that, like the rhythm method, the scientific method is one we should be glad to have in our armoury, but that both have the potential to wreak havoc in the context of a toxic relationship.
