ما خاطرات مردم از 11 سپتامبر را در 25 سال گذشته دنبال کردیم - آنها تا سال 2002 شروع به توهم زدن کردند و هرگز متوقف نشدند.

We followed people’s memories of 9/11 over the past 25 years — they started hallucinating things by 2002 and never stopped

These erroneous memories became stable over time. What most people reported after one year — even if it was wrong — remained when we assessed it later.
