In 2007, Steve Jobs presented the iPhone and the world changed. But for those paying attention, the signals had been there for years: Japanese smartphones, the iPod's success, the growth of mobile internet, the failure of PDAs. The future never arrives without warning — but the signals are often weak, hidden in the noise of the present.
Horizon scanning is the systematic practice of searching for these signals. Used by governments (the UK Government Office for Science has practised it since the 1990s), companies and think tanks, it consists of monitoring diverse sources — scientific publications, patents, startups, cultural movements, policy — to identify emerging changes that could have significant impacts.
Weak signals are events, innovations or trends that seem marginal today but could become dominant. When Satoshi Nakamoto published the Bitcoin paper in 2008, it was a weak signal. When the first climate activists began talking about "degrowth", it was a weak signal. The ability to recognise weak signals — and distinguish them from noise — is one of the most valuable skills for thinking about the future.
How to train this skill? First: diversify your sources. If you only read mainstream news, you'll only see what is already evident. Read scientific journals, follow startups in sectors you don't know, explore cultures different from your own. Second: look for anomalies. The future hides not in linear trends but in discontinuities — events that don't fit existing patterns. Third: connect the dots. A weak signal becomes strong when it intersects with other signals from different domains.
Relatronica's Observatory is designed exactly for this: aggregating diverse sources on ethics, AI, policy and sustainable technology in a single space, facilitating horizon scanning for everyone. You don't need to be a futures analyst — you need to be curious and systematic.
