Experiment results from the National Aeronautics and Space Administration (NASA) Viking1 missions, the Allan Hills meteorite ALH840012 claim of Martian life, and most recently the community debate regarding the claimed detection of phosphine on Venus.3 The Community Workshop Report sets aside the healthy scientific debate that these discoveries generated within the astrobiology community and argues that these examples illustrate a need for systematically increasing the robustness of claims and improving communication both within and outside the field.

Proposals that would reduce flexibility in the scientific process should be subject to strict scrutiny. One potential impact that the assessment framework and reporting protocol as proposed by the Community Workshop Report may have is that confining the search for life and biosignature analysis to a defined structure could inadvertently stifle innovation and debate, especially at the science-development (i.e., proposal)

This begins in pre-Phase A, where mission designers would consider which of the proposed assessment framework questions the mission would address. Also proposed is the creation of a biosignature verification plan, which would outline potential parallel lines of investigation that can be used to assess a potential life detection claim.

However, there are unintended consequences to the specific verification and reporting protocol as proposed by the Community Workshop Report. Parallel Validation Tracks to Publications and Funding Sources The Community Workshop Report asserts "Life detection will … not be an instantaneous process, and it is unlikely to be unambiguous -- yet it is a high-stakes scientific achievement that will garner an enormous amount of public interest"14 and promulgates the idea that life detection requires a special level of verification treatment.

From page 21... ...
The idea of a "Scientific Process + Validation Track" could be perceived as a logical and measured response given the maxim "extraordinary claims require extraordinary evidence."15 The committee agrees wholeheartedly with the Community Workshop Report that life detection is not likely to be instantaneous, not likely to be unambiguous, and will garner substantial public attention. These circumstances may even merit a particular level of caution within the scientific community in dealing with a potential life detection claim.

The Community Workshop Report also recommends that publication disparities between discovery papers and those that provide follow-up research, verification results, and null hypothesis testing contribute to a culture in which verification efforts are not as highly valued. The authors suggest collaboration between the scientific community and publishers to accommodate publication of the caveats and nuances of life detection claims, elevating follow-on publications to the level of the initial publication, and the addition of new publication types that allow for interim progress publications and null hypothesis results.

Despite efforts to increase overall diversity, equity, and inclusivity, problems continue to persist and the space science community is still actively addressing these issues. As an example, NASA and some NSF observatories have implemented dual-anonymous review procedures for its proposal merit review processes in order to prevent bias and promote equity in proposal review.21 The notion of creating an international committee to coordinate verification activities or assess the totality of evidence for life on specific targets is worrying in that it has the capacity to concentrate power in the hands of a few intellectual gatekeepers.

From page 24... ...
The establishment of a new external verification entity to oversee assessment and publication of life detection claims could have unintended negative consequences for open science and for fairness. CONCLUDING REMARKS The committee does consider the assessment framework an excellent first step and a foundation on which future community discussions can build, this Community Workshop Report included.
