Looking back to the survey she did in 1985, 58 % of young people were classified as rooted. That figure had fallen to 43 % in 1988 and to 31 % by 1991. On the other hand, the percentage of pleasure-seeking "trend-following" youth steadily rose from 15 % in 1985 to 36.7 % in 1991, taking this group from third place to the mainstream in a brief six years.
回顧民國七十四年的調查，踏實型的佔了青少年總數中的五十八％，七十七年掉到四十三％，八十年更下降到只有卅一％；相對的，喜歡享樂、追逐流行的從眾型青少年，則從七十四年人數排名第三順位的十五％，逐年上升到八十年的卅六．七％，短短六年間就躍升為主流。
