Tomatoes: The Real Magical Fruit
“Fresh tomato plants! Straight out of the ground! 50 cents each!” I shouted in the school hall. In my hands, I carried a shoebox with little tomato plants. Their homes were plastic bottles, without the top half. Most people ignored my product, but some handed me 50 cents and picked out a 2-week-old baby tomato plant.
About a month before this, I started gardening. I pulled up grass in my little garden for several days in a row. Satisfied with my work, I continued to the second step — begging my dad to take me to the supermarket. He agreed!
When my dad turned off the engine and opened the door, I practically skipped inside the supermarket. We headed straight for the garden center. I picked up planters, seeds and dirt. My dad helped and showed me the best dirt and tomato plant types to get. We got to the register, and my dad, knowing what would happen, helped me pay.
As soon as I got home, I began to plant them in my garden. The following days witnessed my visits to the garden and my parents were amazed by my devotion to my new-found love.
Then was the part where I met my problem — I planted too many tomato seeds. I realized this all too late, about 10 days later when they all started sprouting (发芽) up and I counted 45 tomato plants. A few days went by and then I ended up with 85 tomato plants.
I did what all high schoolers would do when they messed up — I asked people around. I even got a notebook to write down their suggestions. Sadly, I got the same answer from most people, “Just let them die.” WHAT?! Let my beautiful plants die? They had so much potential! They could make 20 — 30 tomatoes per plant! We were talking about the possibility of around 2,550 tomatoes!

Nowadays, people are increasingly interacting with others in social media environments where algorithms control the flow of social information they see. People’s interactions with online algorithms may affect how they learn from others, with negative consequences including social misperceptions, conflict and the spread of misinformation.
On social media platforms, algorithms are mainly designed to amplify (放大) information that sustains engagement, meaning they keep people clicking on content and coming back to the platforms. There is evidence suggesting that a side effect of this design is that algorithms amplify information people are strongly biased (偏向的) to learn from. We call this information “PRIME”, for prestigious, in-group, moral and emotional information.
In our evolutionary past, biases to learn from PRIME information were very advantageous: Learning from prestigious individuals is efficient because these people are successful and their behavior can be copied. Paying attention to people who violate moral norms is important because punishing them helps the community maintain cooperation. But what happens when PRIME information becomes amplified by algorithms and some people exploit (利用) algorithm amplification to promote themselves? Prestige becomes a poor signal of success because people can fake prestige on social media. News become filled with negative and moral information so that there is conflict rather than cooperation.
The interaction of human psychology and algorithm amplification leads to disfunction because social learning supports cooperation and problem-solving, but social media algorithms are designed to increase engagement. We call it functional mismatch. One of the key outcomes of functional mismatch is that people start to form incorrect perceptions of their social world, which often occurs in the field of politics. Recent research suggests that when algorithms selectively amplify more extreme political views, people begin to think that their political in-group and out-group are more sharply divided than they really are. Such “false polarization” might be an important source of greater political conflict.
So what’s next? A key question is what can be done to make algorithms facilitate accurate human social learning rather than exploit social learning biases. Some research team is working on new algorithm designs that increase engagement while also punishing PRIME information. This may maintain user activity that social media platforms seek, but also make people’s social perceptions more accurate.
