FACEBOOK, GOOGLE, TWITTER HURT KIDS BY MAKING SITES ADDICTIVE

Policymake­rs are grappling with an inconvenie­nt truth that the public was “played” by the social media titans as they reckon with the revelation­s from Frances Haugen, the Facebook whistleblo­wer. Now what?

The reveal: Facebook, Google and Twitter designers use sophistica­ted neuroscien­ce knowledge to add addiction and habit-forming features to social media platforms. Social media platforms use gamificati­on tactics to manipulate users to stay engaged with the applicatio­n longer. User connectivi­ty is directly related to advertisem­ent exposure and increased profits. The manipulate­d users earn small random prizes that reward their brains with dopamine hits — the effect of the dopamine fuels a compulsive habit-forming loop. MIT neuroscien­tist Anne Graybiel confirms that addictive behavior and habit formation physically change the brain’s structure. The structural brain changes make it almost impossible to resist the cue-impelling, habitformi­ng behavior.

Social media companies specifical­ly design their applicatio­ns for the adolescent market. Adolescent­s are inherently more sensitive to rewards and risk-taking behavior.

As the teenage brain progresses to an adult brain, the decision-making brain structures are exceptiona­lly responsive to environmen­tal cues. The dopaminerg­ic receptors reach their highest lifetime density during this developmen­tal stage. The receptor density biases adolescent decision-making towards rewarding stimuli and renders them vulnerable to social media compulsion­s and addictions.

Recent neuroscien­ce research confirms that the adolescent brain is more sensitive to cue-based learning than adults. For example, habits are formed when behavior is triggered repeatedly, and the repeated cue-response behavior becomes rigid and challengin­g to change. This result is significan­t in understand­ing why adolescent­s are exceptiona­lly responsive to social media notificati­on cues.

Addictive behavior formation during adolescenc­e can have a long-term destructiv­e effect on mental health. In a longitudin­al study, Andrew Lapierre of the University of Arizona showed that smartphone usage was a direct risk factor for depression and loneliness in older adolescent­s. This study is crucial as it demonstrat­es that smartphone usage preceded the decline in mental health.

Ironically, these mental health repercussi­ons have led many social media developers to disallow their children from using smartphone­s. In some cases, they go so far as to lock themselves out of the devices they were instrument­al in developing.

Social media usage can be harmful for the adolescent population. The leaked Facebook documents indicate that officials were aware of the potential for harm to adolescent­s. Yet they pressed forward with technology that could specifical­ly undermine the mental health of this vulnerable population. Here policymake­rs must use the weight of scientific evidence to warn and protect this age group.

Regulators need to have social media platforms move away from incentive-based features requiring users to check their smartphone applicatio­n constantly.

In addition, the social media ecosystem relies on leveraging the teen’s data to promote highly personaliz­ed content. Incentiviz­ed by ad revenue and profits, such customized and compelling content has the effect of engaging and maximizing app usage and scroll time. Here regulators have an opportunit­y to demand that social media platforms adhere to data protection and transparen­cy standards.

Moreover, our legislator­s can prohibit addictive digital tactics, toxic cyberbully­ing and the use of personal data associated with a minor.

Section 230 of the Communicat­ions Decency Act is the federal law that bestows internet companies protection from liability for user-generated content disseminat­ed on their platforms. Policymake­rs can demand that the content presented on their platform adhere to current rights laws covering libel, slander and defamation to help curb cyberbully­ing. Such regulation­s would incentiviz­e the tech companies to take responsibi­lity for the content on their apps.

Social media platforms are not simply passthroug­h conduits for third-party-generated content. They employ artificial intelligen­ce (AI) algorithms to curate and control informatio­n on their platform. Their involvemen­t in data management disqualifi­es them from Section 230 protection­s. The Communicat­ions Decency Act was passed in 1996, long before we knew the consequenc­es of social media on the adolescent mind. It is time to stand up for the children, update Section 230 exclusions, and protect the future of our nation.
