Criticism of blocking Critics of consensus blocking often observe that the option, while potentially effective for small groups of motivated or trained individuals with a sufficiently high degree of
affinity, has a number of possible shortcomings, notably •
Preservation of the status quo: In decision-making bodies that use formal consensus, the ability of individuals or small minorities to block agreement gives an enormous advantage to anyone who supports the existing state of affairs. This can mean that a specific state of affairs can continue to exist in an organization long after a majority of members would like it to change. •
Susceptibility to widespread disagreement: Giving the right to block proposals to all group members may result in the group becoming hostage to an inflexible minority or individual. When a popular proposal is blocked the group actually experiences widespread disagreement, the opposite of the consensus process's goal. Furthermore, "opposing such obstructive behavior [can be] construed as an attack on
freedom of speech and in turn [harden] resolve on the part of the individual to defend their position." As a result, consensus decision-making has the potential to reward the least accommodating group members while punishing the most accommodating. •
Stagnation and group dysfunction: When groups cannot make the decisions necessary to function (because they cannot resolve blocks), they may lose effectiveness in accomplishing their mission. •
Susceptibility to splitting and excluding members: When high levels of group member frustration result from blocked decisions or inordinately long meetings, members may leave the group, try to get to others to leave, or limit who has entry to the group. •
Channeling decisions away from an inclusive group process: When group members view the status quo as unjustly difficult to change through a whole group process, they may begin to delegate decision-making to smaller committees or to an executive committee. In some cases members begin to act unilaterally because they are frustrated with a stagnated group process.
Groupthink Consensus seeks to improve
solidarity in the long run. Accordingly, it should not be confused with
unanimity in the immediate situation, which is often a symptom of
groupthink. Studies of effective consensus process usually indicate a
shunning of unanimity or "illusion of unanimity" that does not hold up as a group comes under real-world pressure (when dissent reappears).
Cory Doctorow,
Ralph Nader and other proponents of
deliberative democracy or judicial-like methods view explicit dissent as a symbol of strength. In his book about Wikipedia,
Joseph Reagle considers the merits and challenges of consensus in open and online communities. Randy Schutt, Starhawk and other practitioners of
direct action focus on the hazards of apparent agreement followed by action in which group splits become dangerously obvious. Unanimous, or apparently unanimous, decisions can have drawbacks. In
Consensus is not Unanimity, long-time progressive change activist Randy Schutt writes: Confusion between unanimity and consensus, in other words, usually causes consensus decision-making to fail, and the group then either reverts to majority or supermajority rule or disbands. Most robust models of consensus exclude uniformly unanimous decisions and require at least documentation of minority concerns. Some state clearly that unanimity is not consensus but rather evidence of intimidation, lack of imagination, lack of courage, failure to include all voices, or deliberate exclusion of the contrary views.
Criticism of majority voting processes Some proponents of consensus decision-making view procedures that use
majority rule as undesirable for several reasons. Majority
voting is regarded as
competitive, rather than
cooperative, framing decision-making in a win/lose dichotomy that ignores the possibility of
compromise or other mutually beneficial solutions. Carlos Santiago Nino, on the other hand, has argued that majority rule leads to better deliberation practice than the alternatives, because it requires each member of the group to make arguments that appeal to at least half the participants. Some advocates of consensus would assert that a majority decision reduces the commitment of each individual decision-maker to the decision. Members of a minority position may feel less commitment to a majority decision, and even majority voters who may have taken their positions along party or bloc lines may have a sense of reduced responsibility for the ultimate decision. The result of this reduced commitment, according to many consensus proponents, is potentially less willingness to defend or act upon the decision. Majority voting cannot measure consensus. Indeed,—so many 'for' and so many 'against'—it measures the very opposite, the degree of dissent. The
Modified Borda Count has been put forward as a voting method which better approximates consensus. High-stakes decision-making, such as judicial decisions of appeals courts, always require some such explicit documentation. Consent however is still observed that defies factional explanations. Nearly 40% of the decisions of the
United States Supreme Court, for example, are unanimous, though often for widely varying reasons. "Consensus in Supreme Court voting, particularly the extreme consensus of unanimity, has often puzzled Court observers who adhere to ideological accounts of judicial decision making." Historical evidence is mixed on whether particular Justices' views were suppressed in favour of public unity. Heitzig and Simmons (2012) suggest using random selection as a fall-back method to strategically incentivize consensus over blocking. Since consensus decision-making focuses on discussion and seeks the input of all participants, it can be a time-consuming process. This is a potential liability in situations where decisions must be made speedily, or where it is not possible to canvass opinions of all delegates in a reasonable time. Additionally, the time commitment required to engage in the consensus decision-making process can sometimes act as a barrier to participation for individuals unable or unwilling to make the commitment. However, once a decision has been reached it can be acted on more quickly than a decision handed down. American businessmen complained that in negotiations with a Japanese company, they had to discuss the idea with everyone even the janitor, yet once a decision was made the Americans found the Japanese were able to act much quicker because everyone was on board, while the Americans had to struggle with internal opposition. == Similar practices ==
