<P> Some decision - making bodies use a modified version of the colored card system with additional colors, such as orange to indicate a non-blocking reservation stronger than a stand - aside . </P> <P> Hand signals are often used by consensus decision - making bodies as a way for group members to nonverbally indicate their opinions or positions . They have been found useful in facilitating groups of 6 to 250 people . They are particularly useful when the group is multi-lingual . </P> <P> The nature and meaning of individual gestures varies from group to group . Nonetheless, there is a widely adopted core set of hand signals . These include: wiggling of the fingers on both hands, a gesture sometimes referred to as "twinkling", to indicate agreement; raising a fist or crossing both forearms with hands in fists to indicate a block or strong disagreement; and making a "T" shape with both hands, the "time out" gesture, to call attention to a point of process or order . One common set of hand signals is called the "Fist - to - Five" or "Fist - of - Five". In this method each member of the group can hold up a fist to indicate blocking consensus, one finger to suggest changes, two fingers to discuss minor issues, three fingers to indicate willingness to let issue pass without further discussion, four fingers to affirm the decision as a good idea, and five fingers to volunteer to take a lead in implementing the decision . A similar set of hand signals are used by the Occupy Wall Street protesters in their group negotiations . </P> <P> Another common set of hand signals used is the "Thumbs" method, where Thumbs Up = agreement; Thumbs Sideways = have concerns but won't block consensus; and Thumbs Down = I don't agree and I won't accept this proposal . This method is also useful for "straw polls" to take a quick reading of the group's overall sentiment for the active proposal . </P>
