I. Monstrous genes and atoms Flashcards
Define risk in the context of Stirling’s matrix of uncertainty, give an example.
probability of a known event occurring, so knowledge of outcomes and their likelihood are well known. This demands a large amount of good quality and wide-ranging data.
e.g. nuclear plant failure (in theory!), but defo individual health risk like alcohol and smoking
Define uncertainty in the context of Stirling’s matrix.
unmeasurable unknowns; when outcomes or pathways are known, so the hazard is obvious, but probability of this is not measurable nor known.
Define ambiguity in the context of Stirling’s matrix.
when knowledge about the outcomes is weak but it is known whether “something” dangerous is likely to happen or not
Define ignorance in the context of Stirling’s matrix, give an example.
When knowledge about both outcomes and their liklihood is weak -> ignoring or unaware of them both - due to lack of data/info/expertise
Define hazard
events, processes or products that pose a threat to organisms and/or environments
Define pathway
the route a hazard takes to reach a vulnerable recipient
What is an evidentiary approach?
safety as no evidence of harm - easier, faster, assumptions, centralised and expert-led
What is a precautionary approach?
safety as evidence of no harm - slower, hard work, taking care of monsters, more critical, more actors to include, exploration, ‘more exacting burden of proof’
What are the four steps used within risk analyses to reduce the world to measurable knowns or estimations?
- Event, hazard or outcome identification
- Pathways to event known
- Calculation of likelihood of event occurring
- Agreement on implications or acceptability of costs
What are the problems with modernist risk analyses and what should be done instead according to Stirling (2010)?
We are realising that the hazards we face cannot be numerically, confidently calculated nor determined (due to globalizing world) but governments like to present this uncertainty simply, as reducible, calculable, just a small amount of ‘not knowing’.
Instead… Keep it Complex!
Different forms of uncertainty (matrix) need to be acknowledged + we cannot assume only one singular definitive pathway, recognise the role of social choice, varied info.
‘Move towards plural… would help avoid erroneous ‘one-track’, ‘race to the future’ visions of progress’.
What can be used to exemplify the use of the evidentiary approach to risk (that ignores the extent of uncertainty and limits of science)? What did it yield?
Monsanto’s Bt Corn and the EPA’s failed approach to investigating the damage on monarch butterfly populations (amazing trans-generational migration an endangered phenomenon -> climate change, US landuse, pesticides).
Bt Corn: soil organism that produces specific toxins which affect invertebrates i.e. they protect themselves from insects around them. ‘Self-protection gene’ was cut, isolated, inserted into corn.
Resistance to corn borer moth but concerns over harm to Monarch butterfly -> US EPA ran safety trials, declared ‘no detrimental effects were found’
Use of evidentiary approach regarding the detrimental effects on the environment and people
What did a precautionary approach do that the evidentiary one didn’t in the case of Bt corn?
A different team, Cornell University, investigated effects of Bt corn pollen accumulation on neighbouring plants -> if blown on milkweed, bad for Monarch larvae (lab-based though).
What is the evidentiary approach used to communicate but which is in fact philosophically impossible?
Presentation of a certainty of no impact, based on scientific evidence (EPA on Bt Corn - benefits outweigh costs, we’re super sure guys)
What is the precautionary principle? How does this link to Stirling’s (2010) and Latour’s (2011) ideas?
slowing down research process when harm has potential to be huge but uncertain as to how likely it is for this to occur
adopted by EU to make sure science finds evidence of no harm rather than no evidence of harm - demands a slower process with transdisciplinary involvement and expertise beyond science
to ‘slow down’, engage with more groups and forms of knowledge, and regulate the proliferation of monsters, not ignore uncertainty, expand focus (Stirling; Latour)
What can be used to exemplify the potential for new risks in light of the growing power of humans to modify genes? (Nature Special, 2015-17)
CRISPR-Cas9 technology - Nature Special
2015: editing of human embryos, ethical questions rise - potential to eradicate genetic disease before birth?? Unpredictable effects on future generations. Potentially harmful unintended mutations.
2016: (Ledford) ‘wave of new techs made possible’, can alter genes of any genome with ‘unprecedented ease’; ‘exciting the molecular biological community’
2017: could improve IVF, genetic mutations, important insight into biology of human embryos (woo great I hear you say), but if not strictly peer-reviewed, monitored, has potential to be unsafe, unethical, have unintended consequences.
- > the regulatory landscape is shifting, making GM better, easier, safer? Or more dangerous? How are we to know?
