I’ve stayed away from the CRU Swifthack brouhaha, largely because the experts are far better at debunking this denialist crap than I am. But, if there were such a thing as ‘genomic denialists’, they would probably have a field day if they were to get their hands on what we say.
For example, I’m involved in the Human Microbiome Project and we sometimes use phrases like ‘bad data’ or ‘mediocre data.’ I’m not talking about when something goes obviously wrong (i.e., controls fail), but the recognition that the technologies can fall short: technologies designed for genomics where every nucleotide is economically sequenced multiple times have enough errors that the precision of a single sequence is low (error rates can range between 1-5 bases in a 500 base pair read). Throw in chimerism (the creation of hybrid sequences that do not exist due to PCR errors), and if you generate enough sequences, you will get some ‘garbage’ data (see what I mean?).
Does this mean the Microbiome project data are junk? No, we just have to be cautious in our interpretation of the data–we can’t treat every nucleotide in every sequence as ‘canonical’. It certainly does not mean that genomics as a field is fundamentally flawed (feel free to insert joke about why genomics is fundamentally flawed…). But our discussions, both in terms of lingo and the occasional bout of dark humor, could be selectively edited to make us sound very bad.
We also do worry about how to present our findings (doesn’t everyone?). When we were trying to figure out how to work with 454 data (i.e., what is an accurate sequencing read), we had a choice of two presentation styles:
1) We could say that we don’t know what we’re doing and that we generate shitty data, followed with “Damn, we suck ass.”
2) We could say that we’ve solve similar problems with Sanger technology (true) and we are using a similar procedure to solve the 454 problems (we are, and doing so rather well, thank you).
Number #2 is the way to go here.
It is obviously proof of the Grand Genome Konspiracy. But our private discussions about how to present these data could be selectively edited to sound very damning**. And if someone had an axe to grind, or a denialist claim to make, selective editing could be used to create a ‘controversy.’
Just something to keep in mind when you hear about the wellspont of evil that is the email list of the Climate Research Unit of East Anglia (AAAIIIIEEEE!!!!).
**Given that creationists have tried to claim that Stephen J. Gould supported various creationist claims, this level of absurdity by denialists is nothing new.
