哥伦比亚大学实验中得出的“果酱定律”。
如果超市在试吃活动中准备24种果酱，试吃后购买的人只有3%；如果把果酱的种类减少到6种，试吃后购买的人竟然会增加30%。
人在选项多的时候往往会“不做选择”，所以摆24种果酱是卖不出去的（见图2）。

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.
With the help of the Search Filters option, users can now filter search results by type. They can do that by using the new tabs: Media, Links, Files and others. Searches can be done based on the particular time period like by typing in the date or even “Yesterday”. If users type in the name of a person, group, channel or bot, an extra filter will be applied to the searches.
