     23 I've been critical of social media platforms (in spite of my continued
     24 use of them), but I've traditionally defended Instagram. I knew that it
     25 had major problems (most galling, [internal research showed that use of
     26 the platform was hurting teenage girls' body image, and Meta suppressed
     27 the
     28 findings](https://www.wsj.com/articles/facebook-knows-instagram-is-toxic-for-teen-girls-company-documents-show-11631620739?mod=article_inline)),
     29 but browsing IG has nevertheless been a pleasant experience for me.
     30 Photos of my friends' pets, children, and vacations are *nice things*,
     31 and being exposed to them *made me happy*.
     32 
     33 Recently, Instagram instituted changes to the app's main feed, which
     34 were [announced by Adam Mosseri, the head of Instagram, on
     35 Twitter](https://twitter.com/mosseri/status/1521589403671355392). I feel
     36 like Instagram stopped being as fun for me shortly after these changes
     37 were rolled out, so I collected a bit of data.
     38 
     39 ## Method
     40 
     41 Over the course of four days (July 9--12, 2022), I only opened the app
     42 once per day, on my phone. I looked at the first 50 posts on my feed,
     43 and logged a couple features, described below, about each one. I also
     44 gave each post a subjective "sentiment score" using a five-point scale
     45 from -2 (for posts I actively disliked) to 2 (for posts I quite liked),
     46 with a score of 0 being neutral.
     47 
     48 ## Results
     49 
     50 What does Instagram show me? Let's first look at "poster category"
     51 counts, which shows who the posts come from.
     52 
     53 ![Post counts for different categories](poster_category-1.png)
     54 
     55 Most of the 410 accounts I follow are my friends'. I also follow a few
     56 *artists* (a combination of musicians, visual artists, and authors),
     57 *organizations* (primarily political and community orgs), *businesses*
     58 (all of which are run by friends---a couple bakers, a couple shop
     59 owners), and a small handful of *meme accounts* (e.g., "dnddads").
     60 Subjectively, meme accounts are over-represented on my feed; I follow
     61 hundreds of actual people and only around five meme accounts, but the
     62 latter account for over half as many posts as the former.
     63 
     64 The biggest issue here is that the majority of posts come from *accounts
     65 I don't follow*. I understand that Instagram is an ad-supported
     66 business, but I see more ads than posts from friends. Worse still, I see
     67 almost twice as many "suggested posts" as I do posts from friends.
     68 
     69 What types of content are represented by these posts?
     70 
     71 ![Post counts for different media](medium-1.png)
     72 
     73 Mosseri announced that Meta wanted to make video a bigger part of the
     74 Instagram experience, and they seem to have delivered. Of the 200 posts
     75 I logged, the majority were video. Photographs, which the app was
     76 originally designed for, account for a little over a quarter of the
     77 posts, with other types of image (drawings, illustrations, etc.)
     78 accounting for the rest.
     79 
     80 What's the relationship between *poster category* and *post medium*?
     81 
     82 ![Media distribution for poster categories](poster_media-1.png)
     83 
     84 There's a tight correspondence between what medium is employed for a
     85 post and who's posting it. Videos are being pushed by accounts I don't
     86 follow, while my friends continue to prioritize photographs.
     87 
     88 Since post medium and poster category are so tightly linked, I'll focus
     89 on looking at the sentiment by poster category---it would be difficult
     90 to tease apart how I feel about photos vs. videos and how I feel about
     91 posts from accounts I do vs. do not follow.
     92 
     93 ![Sentiment distribution for poster category](category_sentiment-1.png)
     94 
     95 These box-and-whisker plots show the distribution of sentiment scores
     96 for each post category. The heavy vertical line indicates the median
     97 score, and the boxes extend from the first through third quartiles (the
     98 "interquartile range", or IQR). The "whiskers" cover the full range of
     99 scores, unless any observation is identified as a potential "outlier".
    100 Outliers are defined as observations with values more than 150% of the
    101 value of the IQR above or below the third or first quartile,
    102 respectively. For example, I was bothered by a photo of a dead bird
    103 which was posted by a friend, and gave it a score of -1. The first and
    104 third quartiles of sentiment scores for posts from friends are 1 and 2,
    105 providing an IQR of 1. Since -1 is less than 1 (the first quartile) -
    106 1.5 (150% of 1, the IQR), that score is an outlier.
    107 
    108 I'm not surprised that I like posts from the accounts I follow more than
    109 those from accounts I don't. It's disappointing that suggested posts
    110 aren't much nicer to see than ads; these are supposed to make the
    111 platform more "immersive" and "engaging" and fail to achieve that.
    112 
    113 In an attempt to quantify the "experience" of browsing Instagram, I
    114 looked at the cumulative sentiment scores across each of the four days.
    115 There's no doubt that the actual dynamics of my affect, to the extent
    116 that it can even be quantified, is more complicated than +2 + -2 = 0.
    117 However, this is a good first approximation of what it feels like to
    118 scroll through a feed.
    119 
    120 ![Cumulative sentiment over four days](cumulative_sentiment-1.png)
    121 
    122 Each of the four days has a negative cumulative sentiment score, which
    123 indicates that I see more posts that I dislike than posts that I like.
    124 There's also a suggestion of a pattern, in which my sentiment stays
    125 relatively flat and positive over the first 20--30 posts, and then
    126 drops.
    127 
    128 I wonder if this is the result of an intentional design decision by
    129 Instagram. If they have an internal model of what posts I might like,
    130 they could certainly time them in such a way to encourage longer
    131 stretches of engagement, and they have the data to figure out what the
    132 optimal timing would look like. On the other hand, this is a purely
    133 subjective score that I didn't attempt to carefully calibrate, so it's
    134 worth considering that I might just get tired of my feed after a couple
    135 dozen posts.
    136 
    137 ## Conclusions
    138 
    139 I don't know if it's worth an attempt to use my experience to formulate
    140 suggestions to Instagram (or their would-be competitors). I'm
    141 approaching middle age, and I don't spend much money on the internet;
    142 Instagram can get stronger engagement and much better ad conversion
    143 rates from people who aren't like me. Perhaps I'm an unprofitable user
    144 and this is their attempt to nudge me off the platform?
    145 
    146 However, this has been a useful exercise for me, because it suggests a
    147 few things I could change right now to improve my experience:
    148 
    149 -   Stop following meme accounts and organizations (these posts provide
    150     a neutral-to-good experience, but they potentially crowd out posts
    151     from friends and artists that I would enjoy more)
    152 -   Stop scrolling my feed after the first 20 or so posts (cumulative
    153     sentiment appears to begin dropping after this point)
    154 
    155 Most importantly, it calls into question whether I should even continue
    156 using the platform at all. The maximum cumulative sentiment that I
    157 experienced was only six (which corresponds to seeing just three things
    158 that I really like), and that was only achieved on two of the four days
    159 that I measured this. As much as I enjoy seeing photos from my friends
    160 (and the data show that I really do enjoy this), it's hard to conclude
    161 that the experience of using Instagram is joyful.
