Black Lives Matter Protest

Over 55 years have passed since the signing of civil right laws which were supposed to be the panacea for all the ills of raciest abuses faced by the Black-Americans. A lot has increased since for the Black Americans but much more is still to do. They still live in the fear of law enforcement officials who monitor their movement on the street and also in their homes. The blacks are killed  at the lightest alleged provocation by city police without any fear of serious repercussion. The Federals law enforcement agencies also have a history of racist behavior and brutality towards black Americans.

“Black Lives Matter” movement was started in 2013, after a white person named George Zimmerman was acquitted in the shooting death of African-American teen Trayvon Martin in February 2012. The movement got its name as the hashtag #BlackLivesMatter was widely used on social media to protest the acquittal of George Zimmerman.  This movement aims to highlight the injustices, brutality, oppression, gratuitous killings, systemic racism, ruthlessness, bad form, and unaccountably that American culture, particularly law implementation, harbours toward black individuals. Dissenters have pointed out the uncalled intensity of the police, military weaponry, and impulsive usage of the same. The problem of policing in America is more than just individual bad police officers, the culture protects wrongdoers and rewards blind loyalty and is impervious to change. American citizens have recognized these loopholes and will not tolerate these wrongdoings anymore

On 25th May 2020, a 46-year-old black man named George Floyd, died at the hand of a police officer after allegedly using a counterfeit $20 bill at the convenience store. The killing was extensively covered by the cross section of media across the USA and American public saw the horror of the painful death of an unarmed black person by the police. A national-wide protest erupted as millions of people, including whites came out in the streets,  demanding justice for George Floyd. Slogans such as “I can’t breathe”, “All lives will not matter unless black lives don’t”, “Stop police brutality” were raised on the streets across the cities of America. The “Black Lives Movement” which was hitherto mostly confined to a section of blacks youths, quickly expanded to include a wide section of American citizens. 

In his death George Floyd became the symbol of police brutality against the black community in the USA and brought the “Black Lives Matter” from the fringe to the center of American social and political discourse.

Randomised Control Trials and the Alleviation of Poverty in India

Abhijit Banerjee and Esther Duflo won the 2019 Nobel Prize in Economics for their “experimental approach in alleviating global poverty”. Their experimental approach encompassed a variety of novel methods to understand and analyse interventions and Randomised Control Trials (RCTs). Their research has been used by policy makers to make informed policy decisions to best help the marginalised.

What are RCTs?

To understand the effect of a policy, intervention, or medicine, decision makers try to measure the efficacy of the treatment. Do deworming pills given to children improve test scores? Does providing chlorinated water improve the health and economic outcomes of villages? These are some causal (read causal, i.e. caused by, not casual) questions researchers are interested in. The best way to analyse causal effects is to randomise the selection of people in the treatment and the control group (for example: children who are given deworming pills versus children who are not given the pills). This random selection of the two groups removes many statistical biases that might affect the results.

RCTs in India:

Many of the RCTs performed by Banerjee and Duflo were in India. They involved short- and long-term impact assessments of various interventions, policies, models, and treatments. We look at a few RCTs implemented in India:

Teacher absenteeism rates:

Troubled by the low attendance rates (or high absence rates) of public-school teachers in India, Duflo assessed the impact of financial incentives on the absence rates of teachers in Rajasthan. The study monitored teacher attendance by cameras, which was tied to a financial incentive if the attendance was high. From a baseline absence rate of 44%, teacher absenteeism in the treatment group fell by 21%, relative to the control group. High teacher attendance caused child test scores to improve too.

COVID-19 and health-seeking behaviour:

In the context of COVID-19, Banerjee tested the effect of sending messages via SMS that promoted health preserving behaviour. The results were very positive. By sending a short, 2.5-minute clip to 25 million randomly selected individuals in West Bengal, the intervention i) found a two-fold increase in symptom reporting to village health workers, ii) increased hand washing rates by 7%, and iii) increased mask-wearing by 2%. While mask-wearing rates increased only marginally, the spillover effects (wearing a mask stops the virus from infecting more people) were moderately high and positive.

Asset Transfers and the Notion of Poverty:

An RCT by Banerjee in West Bengal involving a productive asset transfer accompanied with training found large and persistent effects on monthly consumption and other variables. The treatment group reported 25% higher consumption levels relative to the control group, who did not receive the asset transfer and training. Implications of such RCTs are huge. The notion that the poor are lazy and unwilling to perform strenuous labour is falsified by this RCT. Often, what the poor lack are opportunities that are hard to come by, given their financial status. A small nudge, like the asset transfer, can cause large and positive effects on their well-being.  

Salt fortification to reduce anaemia:

RCTs also help rule out less cost-effective interventions. Duflo and Banerjee evaluated an RCT which distributed fortified salt in 400 villages of Bihar, to reduce the prevalence of anaemia. However, this intervention found no statistically significant impact on health outcomes like anaemia, hemoglobin, etc.  Thus, while RCTs help introduce novel methods of impacting the lives of the poor, they also help in ruling out in-effective measures. A policy maker might try other alternatives to reduce the prevalence of anaemia.

Are RCTs the gold standard?

Maybe. Extrapolating results from a regional RCT to national policies could present problems. Contextuality matters. A study that indicates positive gains for one region might present different, and rather adverse effects for another region. Nation wide effects might not be as prominent as regional results of a single RCT. The good part is that Banerjee and Duflo have a solution. Just perform more RCTs!
