媒体竞争如何驱动虚假信息传播

2025-06-19 11:37 by 巴比伦Ⅰ:女人

信息爆炸的时代,虚假信息如病毒般在社交媒体和传统媒体中迅速蔓延。从古罗马时期的政治诽谤到现代社交媒体上的假新闻,虚假信息始终是影响公众认知和社会稳定的重要因素。特别值得注意的是,与传统认知不同,研究表明社交媒体并非虚假信息的主要来源,主流媒体和公众人物在虚假信息传播中扮演着更为关键的角色。这种状况引发了一个核心问题:为什么在明知会损害长期信誉的情况下,新闻源仍会传播虚假信息?研究人员发现,媒体间的竞争会形成类似"囚徒困境"的局面:虽然传播虚假信息会损害长期信誉,但短期内能获得更多关注和影响力。这种竞争关系促使媒体陷入"军备竞赛",最终导致虚假信息泛滥。

Should You Buy Bitcoin?

In general, many financial experts support their clients’ desire to buy cryptocurrency, but they don’t recommend it unless clients express interest. “The biggest concern for us is if someone wants to invest in crypto and the investment they choose doesn’t do well, and then all of a sudden they can’t send their kids to college,” says Ian Harvey, a certified financial planner (CFP) in New York City. “Then it wasn’t worth the risk.” The speculative nature of cryptocurrency leads some planners to recommend it for clients’ “side” investments. “Some call it a Vegas account,” says Scott Hammel, a CFP in Dallas. “Let’s keep this away from our real long-term perspective, make sure it doesn’t become too large a portion of your portfolio.” In a very real sense, Bitcoin is like a single stock, and advisors wouldn’t recommend putting a sizable part of your portfolio into any one company. At most, planners suggest putting no more than 1% to 10% into Bitcoin if you’re passionate about it. “If it was one stock, you would never allocate any significant portion of your portfolio to it,” Hammel says.

Unlimited members in Telegram group now

Telegram has made it easier for its users to communicate, as it has introduced a feature that allows more than 200,000 users in a group chat. However, if the users in a group chat move past 200,000, it changes into "Broadcast Group", but the feature comes with a restriction. Groups with close to 200k members can be converted to a Broadcast Group that allows unlimited members. Only admins can post in Broadcast Groups, but everyone can read along and participate in group Voice Chats," Telegram added.
