Sandra Matz: 我研究发现,互联网算法能够通过收集和分析用户的数字足迹,构建出比人类观察到的更全面细致的个人画像。这些数据不仅仅是我们主动发布在社交媒体上的信息,还包括GPS定位数据、购买记录、搜索历史等各种数字足迹。这些看似不起眼的痕迹组合起来,就能揭示出很多信息,例如用户的性格特征、消费习惯、兴趣爱好等等。算法的优势在于其能够处理海量数据,并从中发现人类难以察觉的关联。例如,通过分析语言习惯,可以推断出用户的精神状态;通过分析购买行为,可以预测用户的未来需求。这些信息可以被用于个性化服务,例如精准广告投放、个性化推荐等,也能被用于心理干预,例如帮助用户养成良好的储蓄习惯或改善心理健康。然而,数据收集也存在风险,例如隐私泄露、信息操纵等。因此,我们需要在保护用户隐私和利用数据价值之间找到平衡点。 我个人认为,政策制定者应该简化数据隐私保护流程,并鼓励开发保护隐私的技术,例如联邦学习。联邦学习能够在不收集用户原始数据的情况下,训练出高精度的模型,从而保护用户隐私。同时,我们也需要提高用户的数字素养,让用户更好地理解数据收集和使用的过程,并做出明智的选择。 Maiken Scott: 通过与Sandra Matz的对话,我了解到互联网算法对个人行为的影响是复杂且多方面的。一方面,算法能够提供个性化服务,提高效率,改善用户体验;另一方面,算法也可能被用于操纵用户行为,侵犯用户隐私。我们需要关注算法的潜在风险,并采取措施来保护用户权益。同时,我们也需要认识到,社交媒体等新兴技术对人们的社会交往和心理健康也产生了深远的影响。我们需要批判性地看待社交媒体,并学习如何更好地使用它,避免其负面影响。

Chapters
Sandra Matz discusses her background and introduces the concept of digital footprints, comparing them to her childhood experiences in a small village.
  • Digital footprints are the unique trails of data we leave based on our online activities.
  • Sandra Matz is a computational social scientist who draws parallels between data tracking and her experiences growing up in a small village.
  • Algorithms track our daily activities and create psychological profiles of us.

Shownotes Transcript

We all have digital footprints — unique trails of data based on our online activities that corporations use to predict our behavior and influence our choices. Sometimes, it can be helpful; other times, it can feel creepy and intrusive. On this episode, we talk with computational scientist Sandra Matz about what makes up our digital footprints, what they reveal about us, and how they're being used.Learn more about sponsor message choices: podcastchoices.com/adchoices)NPR Privacy Policy)
