Figure 4.18: Schematic of cost structures in analog and digital experiments.
In other words, digital experiments are not just online experiments. .
By this point,I hope that you are excited about the possibilities of doing your own digital experiments.
Critically, the opportunities to run digital experiments are not just online.
Digital experiments create even more possibilities for field-like experiments. .
This change in scale is because some digital experiments can produce data at zero variable cost.
With that background,I will describe the trade-offs involved in the two main strategies for conducting digital experiments.
Fortunately, the low cost of some digital experiments makes these kind of multi-experiment studies easier.
The second piece of advice that I would like to offer about designing digital experiments concerns ethics.
In conclusion, digital experiments can have dramatically different cost structures than analog experiments. .
This point is so important,I will return to it towards the end of the chapter when I offer advice about creating digital experiments.
Third, relative to some other forms of digital experiments, MTurk experiments cannot scale; Stewart et al.
Read Cialdini's paper, andwrite him an email urging him to reconsider his break-up in light of the possibilities of digital experiments.
The different cost structures mean that digital experiments can run at a scale that is not possible with analog experiments. .
In the 3rd episode of'Hammertime' Alex and Mike talk to Rene, the manager of FabLab,about cool digital experiments taking place in his lab.
In digital experiments, however, these data constraints are less common because researchers tend to have more participants and know more about them.
In between these two extremes there are partially digital experiments that use a combination of analog and digital systems for the four steps.
Now, however, researchers should also organize experiments along a continuum between analog experiments and digital experiments.
Digital experiments can have dramatically different cost structures and this enables researchers to run experiments that were impossible in the past.
In general, analog experiments have low fixed costs andhigh variable costs whereas digital experiments have high fixed costs and low variable costs.
Then, in Section 4.3, I will describe the difference between lab experiments and field experiments andthe differences between analog experiments and digital experiments.
In general, analog experiments have low fixed costs andhigh variable costs, and digital experiments have high fixed costs and low variable costs Figure 4.18.
In digital experiments where researchers partner with companies or governments to deliver treatments and use always-on data systems to measure outcomes, the match between the experiment and the theoretical constructs may be less tight.
In addition to the ethical frameworks guiding human subjects research that I will describe in Chapter 6,researchers designing digital experiments can also draw on ethical ideas from a different source.
Logistically, the easiest way to do digital experiments is to overlay your experiment on top of an existing environment, enabling you to run a digital field experiment. .
In addition to being a nice illustration of the mechanics of experiments, Restivo andvan de Rijt's study also shows that the logistics of digital experiments can be completely different from analog experiments. .
To foreshadow an that will come later when I offer advice about designing digital experiments, there is a final design, called a mixed design, that combines the improved precision of within-subjects designs and the protection against confounding of between-subjects designs.
Just as there are pure lab experiments, pure field experiments, and a variety of hybrids in between,there are pure analog experiments, pure digital experiments, and a variety of hybrids.
As I described in Chapter 5, researchers can increasingly design and build digital experiments with zero variable costs, a cost structure that enables extremely large experiments. .
When researchers already have pre-treatment information,as is the case in many digital experiments, mixed designs are preferable to between-subjects designs because of gains in precision see Technical Appendix.
