推迟、取消、转移到加拿大，这些学术会议为何“撤离”美国

Core Viewpoint - The cancellation or relocation of international scientific conferences originally planned in the United States is seen as a loss for the country, weakening its position in international scientific research and exchange [1][2]. Group 1: Impact on Scientific Community - Researchers express concerns about the increasing difficulties in attending academic conferences in the U.S. due to stricter border control policies, which have led to some conferences being postponed or moved to other countries [1][3]. - The personal nature of scientific collaboration and trust-building is emphasized, indicating that these relationships are hard to establish online [3][6]. - The case of a French scientist being denied entry to the U.S. due to perceived political views has raised alarms within the academic community, highlighting the unpredictable nature of U.S. border control measures [3][4]. Group 2: Conference Relocation and Cancellations - Several international conferences have been moved from the U.S. to Canada or Europe, including the 33rd Annual Meeting of the International Conference on Cognitive Comparison, which will be held in Montreal for the first time outside the U.S. [6][7]. - The International Society for Research on Aggression has announced the relocation of its 2026 conference from New Jersey to Ontario, Canada, due to concerns about attendance if held in the U.S. [6][7]. - The International Association for Cognitive Behavioral Therapy canceled its August meeting in Nashville, Tennessee, citing reduced federal funding and international relations issues as contributing factors [6][7]. Group 3: Broader Implications - The trend of relocating conferences may have long-term effects on the infrastructure and economy surrounding these events, potentially leading to significant losses for individual scholars, research institutions, and host cities [8].
