My own take on this is that this suggests we need more work in this area. We need a follow-up with some follow-up work doing a similar survey, taking sample selection and question design more seriously.
 

Representative quotes from the evaluations

Sampling bias/selection issues

Potential sampling bias – particularly over-representation of safety-minded respondents

There’s a risk that the sample reflects the views of those already more inclined to endorse stringent safety norms. This is particularly important in light of the sample composition, as over 40% of respondents are affiliated with AGI labs

Question selection/design, need for sharper questions

As the authors note, this [agreement] may be partly due to the high-level and generally uncontroversial framing of the statements (e.g., “AGI labs should conduct pre-deployment risk assessments”). But in their current form, the items mostly capture agreement in principle, rather than forcing respondents to grapple with the kinds of tradeoffs that real-world governance inevitably entails. 
For example, would respondents still support red teaming or third-party audits if they significantly delayed product releases?

[Emphasis added]

the paper states that the selected practices are extracted from (1) current practices at individual AGI labs and (2) planned practices at individual labs, among other sources.

... These results might suggest a selection bias where statements selected from labs practices are agreed on by labs themselves,

[suggestion to] introduce an inclusion/exclusion criterion to provide a better justification as to why some statements are selected.

Overstated claims for consensus?

[Paper] “findings suggest that AGI labs need to improve their risk management practices. In particular, there seems to be room for improvement when it comes to their risk governance.”

While one can agree with such claim, it is difficult to see how this conclusion can be reached from the paper’s results.
