社会性动物可以使用社会和私人信息来指导决策。虽然获取社会信息相对经济，但如果对环境线索的关注被无条件复制所取代，则可能会导致适应不良的信息级联。蚂蚁经常利用信息素踪迹（一种社会信息形式）来指导集体过程，这可以包括在选择居住地时做出的共识决策。在这项研究中，我研究了当这些信息源发生不同程度的冲突时，找房蚂蚁如何平衡社会信息和私人信息。社会信息以预先建立的信息素轨迹的形式强烈影响了同等巢穴之间选择的决策过程，并导致搬迁时间减少。然而，当小径通向非偏好类型的巢穴时，当偏好较弱时，社会信息的影响较小，而当偏好较强时，则没有影响。这些结果表明，在该物种的找房过程中，社会信息会与私人信息进行审查。在发生冲突时，私人信息会受到青睐，这可能有助于确保殖民地不会做出代价高昂的错误决定。
Social animals can use both social and private information to guide decision making. While social information can be relatively economical to acquire, it can lead to maladaptive information cascades if attention to environmental cues is supplanted by unconditional copying. Ants frequently employ pheromone trails, a form of social information, to guide collective processes, and this can include consensus decisions made when choosing a place to live. In this study, I examine how house-hunting ants balance social and private information when these information sources conflict to different degrees. Social information, in the form of pre-established pheromone trails, strongly influenced the decision process in choices between equivalent nests, and lead to a reduced relocation time. When trails lead to non-preferred types of nest, however, social information had less influence when this preference was weak and no influence when the preference was strong. These results suggest that social information is vetted against private information during the house-hunting process in this species. Private information is favoured in cases of conflict and this may help insure colonies against costly wrong decisions.
