There's possibly a selection bias in that people are being asked to download and install the app (maybe unhappy people are too listless to get involved?).
However, that doesn't mean the data collected will have no value. We've no idea what they may be comparing the data against so perhaps they'll be able to tackle the question of whether people are really happy, when they say they are.
Also, this is the first example I've seen of researchers trying to use existing devices to run large-scale experiments. I've heard of them but not seen one before. Just being able to complete something on this scale is a win as far as I'm concerned.
- gmac 15y agoYes, the response to this has been far beyond anything I dared hope before launch: over 3 million responses from almost 50,000 volunteers. One of the key benefits of getting panel data using the app is that it doesn't necessarily matter if we get people who are more or less happy than the average. In the analysis, I generally use only the within-individual variation to estimate the effects of different things on happiness.
- amirmc 15y agoSounds good. I was particularly interested since my grad studies were on (positive) emotion and decision making. You're probably aware of it already but I found the following ref interesting for my work. http://www.ncbi.nlm.nih.gov/pubmed/12930487 http://www.ncbi.nlm.nih.gov/pubmed/12930487
