Careful readers will note that the online versions of six articles from IEEE Spectrum’s January “Top Tech 2015” prediction issue offer them a chance to make their own technology forecasts. At the ends of these articles you’ll find boxes with links to questions on robotics, solar power, the Google Lunar XPrize, exascale computers, drones, and smart cars. These lead to SciCast, the prediction market project co-founded by Charles Twardy, Kathryn Laskey, and Robin Hanson at George Mason University.

SciCast lets participants bet points on specific outcomes of questions in science and technology, testing their judgment against thousands of others’ and reaping rewards if their prognostications are better than those of their competitors. Anyone can browse SciCast to see what participants think the future will bring. And anyone can play. Registration is required to make forecasts and join the game, but it’s minimal and free. You just need to pick a username and password. Even an e-mail address is optional. You may be asked for more information, or to complete a simple questionnaire to gauge general scientific and technical literacy, but whether you respond or not is up to you.

The George Mason team built SciCast with support from the U.S. Intelligence Research Projects Activity. It’s one of tools for staying ahead of world events, political and scientific. SciCast focuses on the sci-tech part, and is one of three approaches that have “produced notable results,” according to the Wall Street Journal.

This kind of competition works because it helps eliminate bias and the kind of herd mentality that can seize small groups of experts. As the Journal went on to say:

Deliberation is useful, but it isn't ideal for generating accurate forecasts: It is susceptible to groupthink. Social biases, such as deferring to those with seniority, intrude on the process. And dissenting views often aren't captured. The effects have led analysts to predict events that didn't occur, or miss events that did take place.

In his best-selling The Signal and the Noise: Why So Many Predictions Fail—but Some Don’t, American prognostication guru Nate Silver talked about eliminating bias.

If we want to reduce these biases— we will never be rid of them entirely— we have two fundamental alternatives. One might be thought of as a supply-side approach —creating a market for accurate economic forecasts. The other might be a demand -side alternative: reducing demand for inaccurate and overconfident ones.

A prediction market is the supply-side solution. It lets forecasters work in relative anonymity and isolation, motivated solely by self interest (in theory, at least) as they try to amass the most points. Every bet they make changes the odds: SciCast’s FAQ says that “forecasters spend points to adjust the consensus forecast. Significant changes cost more — but ‘pay’ more if they turn out to be right. So better forecasters gain more points and therefore more influence, improving the accuracy of the system.”

So those out for point-gain and bragging rights can start with these articles, and the associated SciCast questions:

Special Report: Top Tech 2021

After months of blood, toil, tears, and sweat, we can all expect a much better year

Last January in this space we wrote that “technology doesn't really have bad years." But 2020 was like no other year in recent memory: Just about everything suffered, including technology. One shining exception was biotech, with the remarkably rapid development of vaccines capable of stemming the COVID-19 pandemic.

This year's roundup of anticipated tech advances includes an examination of the challenges in manufacturing these vaccines. And it describes how certain technologies used widely during the pandemic will likely have far-reaching effects on society, even after the threat subsides. You'll also find accounts of technical developments unrelated to the pandemic that the editors of IEEE Spectrum expect to generate news this year.
