We had a little natural experiment.
Natural experiments take advantage of random events in the world.
What we saw was a natural experiment.
Two approaches that especially benefit from the digital age are matching and natural experiments.
However, the analysis of natural experiments can be quite tricky.
This is an example of research using a natural experiment.
Like natural experiments, matching is a design that also benefits from big data sources.
What do you mean by a natural experiment?
Well, there's a natural experiment right there, you get to observe the development of a human infant.
This approach is called natural experiments.
So this sets up this beautiful natural experiment where we can look at the genes behind our vision, and at the very roots of how we can see.
Random event+ always-on data system= natural experiment.
In practice, the confidence we have in natural experiments frequently hinges on the plausibility of this“as-if” random claim.
(2014) were exploiting what could be called an Emotional Contagion natural experiment.
This is an example of research using a natural experiment. Source: Wikimedia Commons.
To test this idea,Snow took advantage of what we might now call a natural experiment.
With natural experiments researchers have less control over things like recruitment of participants, randomization, and the nature of the treatment.
For more on using the Vietnam draft lottery as a natural experiment, see Berinsky and Chatfield(2015).
Fair comparisons can come from either randomized controlled experiments or natural experiments.

But, there are many situations where you can't run the ideal experiment andnature has not provided a natural experiment.
For machine learning approaches that attempt to automatically discover natural experiments inside of big data sources, see Jensen et al.
Moving further away from randomized controlled experiments, sometimes there is not even an event in nature that we can use to approximate a natural experiment.
For example, evidence from natural experiments is not always as clean as evidence from randomized experiments and boosting might have been more logistically difficult to implement than block.
Researchers, however, do not control the schedule of workers in any real business, and so Mas andMoretti had to rely on a natural experiment which took place in a supermarket.
Often natural experiments are the best way to estimate cause-and-effect relationships in settings where it is not ethical or practical to run randomized controlled experiments. .
In terms of the first R(Replacement), comparing the Emotional Contagion experiment(Kramer, Guillory, and Hancock 2014) andthe emotional contagion natural experiment(Coviello et al. 2014) offers some general lessons about the trade-offs involved with moving from experiments to natural experiments(and other approaches like matching that attempt to approximate experiments in non-experimental data, see Chapter 2).
For example, evidence from natural experiments is not always as clean as that from randomized experiments, and boosting content might have been logistically more difficult to implement than blocking content.
In terms of the first R(“replacement”), comparing the emotional contagion experiment(Kramer, Guillory, andHancock 2014) and the emotional contagion natural experiment(Lorenzo Coviello et al. 2014) offers some general lessons about the trade-offs involved in moving from experiments to natural experiments(and other approaches like matching that attempt to approximate experiments in non-experimental data; see chapter 2).
