付费社群卖不动了吗?
3 6 Ke· 2025-05-14 23:56
每年五六月份,都是许多付费社群/圈子纳新、续费的日子。 其中有不少付费社群,一年营收都在四五千万以上。 比如在杭州,说得上名字的,一年靠收取会员费在1000万以上的不下10个。 以前朋友圈都会出现刷屏的现象,但是今年以来,明显感受到整个付费社群市场低迷了很多。 01 参加活动和付费都不积极了 某万人付费社群就在我公司附近,前几天和他们老板吃饭聊天。 以前4月份续费的时候,预约第一天就能有1万人,意味着至少1000万的收入。 但是今年预约时间过了3天,才只有6000多人,掉了40%。 许多生意本质上就是在赚信息差、认知差的钱。 但是对于许多普通用户来说,单纯的掌握信息是发不了财的。 还有个付费社群在滨江区,他们费用比较便宜,一年四五百块钱,也是一个万人社群。 前几年,许多会员帮他们做分销,都能赚几万块钱。 今年拉新第一名的会员,才赚了几千块钱,也就拉了六七十人。 像他们这种几千人、上万人的付费社群,每年三、四月份都会开一场线下大会。 一方面是为了总结表彰,另一方面是为了今年的拉新续费造势。 以往做活动,可谓是一票难求,许多人非会员加价都要来现场。 但是今年,运营私信都戳烂了,还有很多门票卖不出去。 02 用户对 ...

Core Viewpoint - Honor is shifting its focus towards the mid-to-low-end smartphone market, launching new models like the Power series, which features a competitive price point and large battery capacity, indicating a strategic pivot from its previous high-end positioning [1][3][7]. Market Position and Competition - Honor's market share in China has been declining, with IDC reporting a drop to 13.7% in Q4 2024, placing it fifth in the domestic smartphone market [4][5]. - The competitive landscape is dominated by major players like Xiaomi, Huawei, OPPO, vivo, and Apple, with Honor's brand recognition and fan base being relatively weak compared to its competitors [3][4][10]. Strategic Changes - Following a leadership change, Honor has introduced the "Alpha" strategy aimed at creating a global AI terminal ecosystem, which marks a significant shift in its operational focus [6][13]. - The company plans to invest $10 billion over the next five years to build this ecosystem, which is expected to enhance its brand positioning and market competitiveness [13][14]. Product Strategy - The new Power series is designed to cater to the mid-to-low-end market, featuring an 8000mAh battery, which is a key differentiator in a crowded market [16][22]. - Honor's pricing strategy has been adjusted to leverage government subsidies, making its products more appealing to cost-sensitive consumers [19][24]. Market Trends and Consumer Behavior - The introduction of government subsidies has positively impacted smartphone sales, with a reported 5.6% year-on-year growth in China's smartphone shipments for 2024 [20][26]. - Consumers are increasingly inclined to purchase mid-range smartphones, which presents both opportunities and challenges for Honor as it competes in a highly saturated market [25][30]. Challenges Ahead - Despite the potential benefits of the subsidy program, increased competition in the mid-range segment poses a significant challenge for Honor, as it must differentiate itself from established competitors like Xiaomi and OPPO [23][29]. - Honor's historical association with Huawei may hinder its efforts to establish a distinct brand identity, complicating its strategy to cultivate a loyal customer base [15][28].
信“心”心理问答|面对别人的恶意,为何“我”总害怕反击
Jing Ji Guan Cha Bao· 2025-05-14 01:44
(原标题:信"心"心理问答|面对别人的恶意,为何"我"总害怕反击) 读者来信: 最近发生的一件事让我意识到,自己似乎陷入了一种难以摆脱的困境:当他人对我释放恶意时,我第一 反应不是反抗,而是恐惧 —— 甚至会因害怕激怒对方而选择沉默。这种矛盾的心理让我既痛苦又困惑。 上周,我在工作会议上被同事当众嘲讽: " 你的方案根本行不通,别浪费大家时间。 " 那一刻,我感到 血液涌上头顶,喉咙像被堵住一样说不出话。散会后,我反复回想他的话,明明觉得他的批评毫无根 据,却始终鼓不起勇气反驳。更让我羞愧的是,当晚我辗转反侧,甚至担心他第二天会变本加厉。 这种反应并非偶然。从小到大,类似的事情反复发生。 你提到自己害怕反抗会招致更猛烈的攻击,这让我想起了许多来访者曾经的描述:他们内心深处都住着 一个"恐惧的小孩",时刻都在担心"如果我反抗,父母或者某某人会不会就不要我了"。这种对"被抛 弃"的深深恐惧,让你宁愿选择默默吞下委屈,也不敢去打破那个看似安全的"沉默契约"。 我似乎天生对 " 冲突 " 充满恐惧,害怕自己的反击会招来更猛烈的攻击,害怕被孤立,更害怕面对 " 如果 反抗无效怎么办 " 的绝望。 我也并非毫无行动,我告 ...
哈佛新论文揭示 Transformer 模型与人脑“同步纠结”全过程,AI也会犹豫、反悔?
3 6 Ke· 2025-05-12 00:22
近日,来自哈佛大学、布朗大学以及图宾根大学研究者们,共同发表了一项关于Transformer模型与人类认知处理相关性的研 究论文: ——《Linking forward-pass dynamics in Transformers and real-time human processing》 意译过来就是:Transformer模型的"思考过程"与人类大脑实时认知的奇妙相似 问题来了:AI和人类,不只是最后的选项,连中间的"挣扎"和"转变"也能被对齐吗? 这篇论文的作者,换了个角度:不只看AI模型的输出,还要扒一扒Transformer每一层的"处理动态",与人脑处理信息的"实时 轨迹"是否能对上。 01 AI和人脑,真的在"想"同一件事吗? 换句话说,它想搞清楚一个"老问题":AI模型的内部处理过程,和人类大脑的实时认知,有多少相似? 过去我们研究AI和人类的相似性,最常见的做法是什么?"看结果":让AI做题,看它答对多少,概率分布和人的选择对不对 得上。例如,让GPT写作文、识别图片、做逻辑推理,然后对照人类的数据,得出一个"AI越来越像人了"的结论。 但这其实只是表象。 想象一个场景:在答一道不太确定的 ...
如何减少内心压力,避免“凡事都往最坏处想”
3 6 Ke· 2025-05-12 00:06
Core Viewpoint - The article discusses the common cognitive pattern of "catastrophizing," where individuals tend to imagine the worst possible outcomes in various situations, leading to unnecessary anxiety and distress [2][3][4]. Group 1: Understanding Catastrophizing - Catastrophizing is described as a thought process where individuals assume the worst outcomes are likely to happen, often leading to feelings of anxiety and fear [2][3]. - This cognitive distortion is linked to various anxiety disorders, including depression, eating disorders, and obsessive-compulsive disorder [4]. - Recognizing the tendency to catastrophize can help individuals understand the triggers of their anxiety and fear [4]. Group 2: Causes and Effects - Factors contributing to a propensity for negative thinking include overprotective parenting, exposure to extreme events, and personal experiences of trauma [4]. - Catastrophizing can provide a false sense of control over uncontrollable events, making individuals feel more cautious [5][6]. - The article emphasizes that while occasional negative thoughts are normal, persistent catastrophizing can severely impact daily life [4][5]. Group 3: Strategies for Managing Catastrophizing - The first step in managing negative thoughts is to recognize when they occur, often accompanied by feelings of anxiety and fear [7]. - Writing down these thoughts can help individuals identify patterns and challenge the validity of their fears [7][10]. - Techniques such as questioning the accuracy of negative thoughts and considering alternative, more realistic outcomes can help mitigate the effects of catastrophizing [10][11][14]. Group 4: Cognitive Behavioral Techniques - Cognitive Behavioral Therapy (CBT) and Rational Emotive Behavior Therapy (REBT) are suggested as effective methods for addressing catastrophizing [6][10]. - Practicing exposure therapy by imagining worst-case scenarios can help individuals confront their fears and reduce anxiety over time [18]. - Keeping a journal to track distressing thoughts and their triggers can aid in recognizing and replacing negative thought patterns with healthier ones [17].
