Date China gathers 1B citizen genomes.
New York Times (June 17, 2020) has an article on how the Chinese state is collecting a massive genomic database of 700 million men (full population coverage). This is used in order to fight crime, so far resulting in captures of otherwise elusive criminals (similar to in the USA, e.g. Golden State Killer). The database will also present the Chinese government with enormous statistical power for genomics research that could be used to train very accurate genomic prediction models for medical and eugenic purposes (artificial selection). British intelligence researcher Richard Lynn speculated already back in 2001 that China would pursue such eugenic technology in the first half of the 21st century. In 2018, Chinese researcher He Jiankui caused a shockwave when it was revealed he had genetically altered embryos and which were later born as healthy babies. Many Western governments or government bodies are also pursuing large-scale genome biobank projects (e.g. US Million Veteran Program), though not so far at the scale of the Chinese program. Private consumer companies are also building massive databanks.
The question is: When will the Chinese government have gathered genome-wide data on 1 billion citizens?
This question resolves positively when a reputable scientific source reports that Chinese has reached 1 billion genotyped or sequenced genomes from their own citizens (a reputable source is e.g. Nature News, MIT Tech Review, or similar, as well as any reviewed paper in the unlikely event that it is reported in a journal before a science news source).
The date for resolving is the one where this goal was reached, not the reporting date. For the purpose of this question, whole genome sequencing and whole-genome microarray technology count
By citizens, we mean citizens of Mainland China, Macau and Hong Kong
Genomes from monozygotic (identical) twins count as multiple different genomes for the purpose of this question
Genotyping only counts if it is both broad (samples widely in the genome), and deep (samples many loci, say >500k).
Metaculus help: Predicting
Predictions are the heart of Metaculus. Predicting is how you contribute to the wisdom of the crowd, and how you earn points and build up your personal Metaculus track record.
The basics of predicting are very simple: move the slider to best match the likelihood of the outcome, and click predict. You can predict as often as you want, and you're encouraged to change your mind when new information becomes available.
The displayed score is split into current points and total points. Current points show how much your prediction is worth now, whereas total points show the combined worth of all of your predictions over the lifetime of the question. The scoring details are available on the FAQ.
Note: this question resolved before its original close time. All of your predictions came after the resolution, so you did not gain (or lose) any points for it.
Note: this question resolved before its original close time. You earned points up until the question resolution, but not afterwards.
This question is not yet open for predictions.
Metaculus help: Community Stats
Use the community stats to get a better sense of the community consensus (or lack thereof) for this question. Sometimes people have wildly different ideas about the likely outcomes, and sometimes people are in close agreement. There are even times when the community seems very certain of uncertainty, like when everyone agrees that event is only 50% likely to happen.
When you make a prediction, check the community stats to see where you land. If your prediction is an outlier, might there be something you're overlooking that others have seen? Or do you have special insight that others are lacking? Either way, it might be a good idea to join the discussion in the comments.
