The SIFT method

SIFT方法

S - Stop: Don't immediately share or use unverified information I - Investigate the source: Who is behind the information? F - Find better coverage: What do other reliable sources say? T - Trace claims: Find the original source of the claim

S - 暂停：不要立即分享或使用未验证的信息 I - 调查来源：信息背后的主体是谁？ F - 查找更权威报道：其他可靠来源的说法是什么？ T - 追溯主张：找到主张的原始来源
