人們常說，眼睛是心靈的窗戶。事實上，Instagram也可以是心靈的窗戶。研究人員表示，他們研發了一個算法，可以利用社交媒體上發布的消息，比醫生更有效地確認一個人的抑郁狀況。

佛蒙特大學的克里斯·丹佛斯和哈佛大學的安德魯·里斯在EPJ Data Science期刊上發表了他們的發現。他們稱自己開發的工具會掃描Instagram發布的消息，受試者被檢測出抑郁的成功率高達70%。相反，醫生只有42%的概率能準確判斷情況。

為了獲得這些結果，丹佛斯和里斯的團隊研究了166個受試者在Instagram上發布的4.4萬張圖片。受試者中有71名過去被檢測出患有抑郁癥。通過分析色彩、使用的濾鏡和人物的表現，研究者可以確定他們所謂的“抑郁標志”。例如，患有抑郁癥的用戶更傾向于發布顏色灰暗的照片，使用黑白的水墨濾鏡的可能性也更大，盡管整體來看他們不太喜歡使用濾鏡。另一方面，沒有抑郁癥的用戶更喜歡巴倫西亞濾鏡，這會讓圖片更加鮮艷。

令人驚訝的是，抑郁癥患者更傾向于發布帶有人臉的照片。（由于論文作者沒有確證照片中的人是誰，所以還無法確定抑郁癥患者是否更愛自拍。）（財富中文網）

It's often said that eyes are a window into the soul. Instagram, it turns out, can be that window, too, as researchers say they've developed an algorithm that uses posts on the social media network to identify depression more effectively than doctors can.

Chris Danforth of the University of Vermont and Andrew Reece of Harvard University published their findings in the EPJ Data Science journal. The tool they built to scan Instagram posts, they said, could accurately identify depression in 70% of their study's participants. Doctors, on the contrary, are successful only 42% of the time.

To arrive at these results, Danforth and Reece's team looked at roughly 44,000 Instagram photos posted by 166 study participants — 71 of whom were diagnosed with depression in the past. Analyzing factors such as hue, the use of filters and the presence of people, researchers were able to determine what they call "depression markers." Depressed people, for example, were more likely to post photos with darker, grey colors. Of those tones, the black and white Inkwell filter was more likely to be chosen, though depressed people on the whole were less likely to choose filters to begin with. People who aren't depressed, on the other hand, preferred the Valencia filter, which brightens the image.

Surprisingly, depressed people were more likely to post photos with faces in them. (Because the authors didn't determine who the photos were of, they couldn't say if that correlation meant the depressed people took more selfies.)
