各类运动的观众行为呈现恶化趋势，事件涵盖板球、高尔夫与网球。Ryder Cup 在2024 年出现向球员投掷啤酒与辱骂的情况，Wimbledon 程度较轻但美网与法网均有球员投诉，Australian Open 同样受到干扰。历史脉络显示这并非新现象：1985 年已有纪录指出「嘲骂与辱骂上升」、幽默减少。个案亦显示单一观众可连续多年干扰同一球员。2023 年 Lord’s 的 Bairstow 争议甚至使英澳两国领导人介入，部分 MCC 会员因此被长期禁赛。
统计资料显示酒精因素增加风险。美国大学橄榄球场馆中，能贩售啤酒的学校从 2018 年的 20 所增至 2023 年的 55 所；高尔夫 Waste Management Phoenix Open 更在 2024 年因酗酒失控而暂停酒精贩售。澳洲场馆为降低风险，在多日板球赛中仅售中度酒精啤酒。心理研究指出，高度认同球队的观众在表现不佳或面临威胁时更易失序。然缺乏可量化统计，因骂声、辱骂与情绪性行为无系统记录。
长期趋势显示敌意并非新生，而是「通膨式」扩大。1950 年代职业高尔夫球员即曾在美国遭遇观众拍手欢呼其失误。当代差异在于规模与商业化：男子运动常受酒商与博彩商赞助，使场馆文化更粗鄙。专家认为变动的社会同理心与公共礼貌标准，使现代观众更易越界。虽多数观众仍守规矩，证据显示各类运动的顶尖选手所承受的敌意强度与频率均较过去更高。
Across sports, fan misconduct has intensified, spanning cricket, golf, and tennis. The 2024 Ryder Cup saw thrown beer and verbal abuse; Wimbledon remains mild, but the US Open, French Open, and Australian Open drew player complaints. Historical accounts show continuity: a 1985 analysis noted rising jeering and declining humor. Individual cases demonstrate persistent harassment across years. The 2023 Bairstow incident at Lord’s escalated to national political involvement, with MCC members receiving long bans.
Quantitative indicators show alcohol as an accelerant. In US college football, stadium beer sales expanded from 20 programs in 2018 to 55 in 2023; the Waste Management Phoenix Open suspended alcohol sales in 2024 due to disorderly conduct. Australia limits beer strength during multi-day matches. Psychology research links strong team identification to higher odds of misbehavior under threat or poor performance. Yet measurement remains poor because insults and verbal aggression lack systematic tracking.
Long-run evidence shows hostility is not new but has expanded “with inflation.” In the 1950s, professional golfers already faced crowds cheering their errors. Modern differences stem from scale and commercialization: men’s sports often feature alcohol and gambling sponsors, shaping rowdier environments. Scholars argue that shifting social norms in empathy and civility make boundary-crossing more common. While most spectators behave appropriately, cumulative evidence indicates that today’s elite athletes face higher intensity and frequency of hostility than prior generations.
