Is virtual reality the answer to big financial and health questions? Researchers think it could be.
The financial decisions you make today will affect you for the rest of your life. So what if you could get a little insight into just how those decisions might affect future you? That’s what Dan Goldstein, principal researcher with Microsoft Research, is doing. We sat down with Dan to figure out how he is helping people and companies make better decisions with the help of virtual reality technology.
Can you explain what it is you do?
I’m a principal researcher at Microsoft Research, which basically means I’m a professor. Microsoft Research is like a university without the students. So we have a lot of PhDs and a lot of former professors here that are doing basic research on interesting topics. The field I’m interested in is economic behaviour and I answer questions about people’s economic behaviour using techniques and tools from computer science—my academic background. In particular I have found that virtual reality has real promise for understanding and shaping people’s economic decision-making on a personal level.
You have a degree in computer science but went back to school for psychology?
Yep. I have degrees in computer science and experimental psychology.
Did computer science lead you to psychology or is that something you’ve always been interested in?
I guess I’ve always been interested in both. My father was an experimental psychologist and I kind of grew up using computers so I thought the best way to study behaviour and create tools that influence behaviour is to use computer technology.
I was surprised that virtual reality technology has applications in finance. When you started researching VR technology did you think it would have as big as an effect on you and your research?
I was thinking about saving and retirement for some time. I was working with William Sharp, who is a Nobel Laureate whom I met when I was visiting Stanford University. He put me in touch with Hal Hershfield, who’s my coauthor on the paper about using VR. He had been thinking a lot about using VR to help people think about the future and I had been creating these electronic decision calculators to help people think about their future finances. So we just put them together and thought “Oh, we could take what you’re doing and what I’m doing and put them together into a VR system to help people think about their future finances.” That’s how it was born.
What’s neat about VR is it can take the way something is now and change it in a certain way. So, in particular, what we do is take the present and we use VR to show what the future might be like based on the present. For instance, based on how you look right now, we can use VR software to determine how you’ll look 30, 40 years in the future.
Now why this is interesting for economics is that a lot of economic decisions involve making tradeoffs between doing things now and doing things in the future. Saving is a classic example of this. You can spend money now, in which case you’re not going to have money to spend in the future, or you can save money now, in which case you will have money to spend in the future. The problem, while we know this, is it’s really hard to think about how our actions today will affect ourselves in the future. For instance, you don’t know if you spend an extra five bucks a day every day if that will leave you poorer in the future or if it will make no difference. But computers are very good at figuring that kind of thing out.
Similarly, it’s hard to imagine how the future might look. We tend to neglect or disbelieve that we’re going to get old.
But when a computer takes a photo of you and ages it, it makes it quite easy to look at it and say, “Oh, yep, that’s me. I really do need to think about the fact that there’s a future me out there, and future me is going to inherit all of the decisions I make today.”
It’s equal parts helpful and a little scary to think that $4 cup of Starbucks you buy every day could be affecting whether or not you have a comfortable retirement.
Right. And part of what’s scary is that you don’t really know if things like that do matter or don’t matter. You don’t want to worry too little and you don’t want to worry too much. You want to worry the right amount. That’s what technology is great for. It’s great for doing projections and letting you know this aspect of your life that you can change really has a consequential effect on the future you whereas this thing, that you may be spending time optimizing, doesn’t really matter either way: you might as well forget about it and do what makes you happy.
How many people decide to save more after using your technology?
We know that in our experiments people said that they would save about 50 per cent more for retirement after being shown an image of themselves aging compared to a group that was not shown an image of their future selves. So we think that’s promising and what’s nice about it is that every employer typically has a picture of every employee and it is in the employer’s office where the employee is making this decision of how much to save for the future. We also know that most people never change that decision they make in that first week of work when they decide how much of their paycheck they want to contribute to their retirement fund.
I’m guilty of that.
Like 90 to 100 per cent of people never change what they set up in the first week. But if you can show them that aged picture in that moment when they are making the decision, that causes them to save 50 per cent more, and they stay in that job for 10 to 20 years, that’s going to have a huge impact on the amount of money they have saved by the time they retire.
We’ve been working to try and do field studies—we don’t have anything completed yet—with companies. But that’s one of our goals, to get this in front of people when they are making that decision because one little nudge at the right moment could boost their savings.
You mentioned briefly that you see other applications for this technology. What are some of those other research uses for VR technology?
We’ve shown people their future face, and now we’re showing people their future body, if you will. This is also work that I’m undertaking with Hal. A lot of medical spending is due to behaviours that people have as opposed to inherited conditions. So things like smoking, being overweight, not exercising are behaviours that can lead to health problems that can be very expensive to our society. Since these are behavioural problems, there might be behavioural solutions to help people.
This future body experiment, which we are running right now, involves people who are trying to lose weight. What we have created is a system by which they can step on their scale in the morning—their scale is tracking their weight day by day—and when they start to gain weight, they’ll get an email that shows a rendering of how their body will look if they continue to gain weight. So they’ll see a heavier version of him or herself.
At the same time, if they are overweight and doing a good job losing weight, they will be emailed a computer rendering of how their body will look if they continue to lose weight. It’s using positive reinforcement and negative reinforcement by showing you that your body is heading in a certain direction but you’re getting that feedback immediately—within a few days of the weight gain—as opposed to the situation we face in everyday life: we gain weight very slowly and then we look down a year later and realize we’ve gained 20 to 30 pounds. This lets you glimpse into the future by sending you an email from the future of how you might look if you continue down the road that you are heading. The basis of the experiment that we are running is to see whether these kinds of images from the future—if you will—will motivate people to lose weight.
Seems similar to your finance research in that it can be helpful and a little bit scary about how much they may have gained in a specific time and what that means for the future.
We’re trying to be careful to not make it too sensitive to irrelevant changes in weights, but respond to what we think are trends that they need to be concerned about.
Do you think this type of VR technology has any other business applications?
I think the health thing is definitely a business application. Companies are the ones paying for the bad health outcomes often caused by behaviours that people have. Getting people healthier can lower the cost of providing insurance to people, which is a big part of the economy.
What would you say is one of the most beneficial uses of VR today?
I’d like to think that the financial aspect is the most beneficial. Humans aren’t used to thinking about compound interest, correlations between asset classes and things like that, whereas we can simulate out pretty well using computers financial futures and represent this back to them in a way that is easy for them to understand. I think that right now this is where we are seeing the biggest benefits, but I also think we are going to be thrilled and delighted by the kinds of things VR researchers are dreaming up and trying out to address a myriad of problems in life.
I’ve heard of people using VR and AR headsets to help get rid of the fear of public speaking. You put on this headset that makes you feel like you are in a lecture hall with 300 people and you can practice your speech and get a feeling for what it’s like to address a room with a large audience. Any kind of situation which is expensive to reconstruct in reality might be inexpensive to construct in virtual reality.
What are your hopes for the future of VR?
My focus has always been on decision making, so I really hope that for the future of VR that it can promote better decision making by just making it easier on our brains— showing us the outcomes that could happen as opposed to us trying to imagine these outcomes ourselves since our imagination may be inaccurate or uninformed.
Do you think this is something that could lead people down a rabbit hole of VR?
That they will turn to technology for an opinion on everything?
I hadn’t really thought about it as a potential problem. We’re trying to take the most consequential decisions people face and tackle those first. That’s why we’re starting with things like your health and your finances. In the future we see people working with this technology to make big decisions. But I can see smaller decisions being aided with virtual reality in a way that wouldn’t necessarily constitute a problem. For instance, if you could “try on” clothes using VR, see how they look and fit, and by doing it in the VR way in five minutes saves you a three hour trip to the mall and buying something and trying it on and returning it, I think that’s a good use of people’s time. If you’re making good decisions in less time then its freeing up time to do other things.
What does a normal day as a Principal Researcher at Microsoft Research look like?
When I was a professor, I was teaching, I was doing university administration, and I was doing research. Now the first two are gone and I’m just
doing research all the time, which is a dream for me.
But what that means in exact terms is that on a typical day I’m meeting with collaborators, we’re designing experiments and running experiments, working out the logistics with partners if its a field experiment. Once the data are in I’m analyzing the data, doing statistical analysis on it, graphing it, figuring out the best visualization, writing it up in the form of academic papers, and submitting those papers for publication.
Can you give us a preview of the talk you’ll be giving at the Amplify Festival in Australia?
I’m going to be talking about what makes self-control hard, and share some solutions that people have come up with to level the playing field between the present and the future self and show some of the technologies that my colleagues and I have created to assist in these decisions. Some of these I’ve talked about before, as well as some new ones that we’ve been developing since then.
Dan Goldstein is a Principal Researcher at Microsoft Research in New York City and Honorary Research Fellow at London Business School in the UK. He will be speaking at the Amplify Festival in Sydney on Tuesday 2nd June. Click here to find out more about the festival.
