Technology and machines are becoming more and more like us as they advance. But this mimicry is already crossing over to our darker prejudices, adopting the same biases that have plagued society for so long.
Machine learning, which is the most rapidly advancing application of AI, is today utilized everywhere from pointlessly fun app features like Snapchat filters to gravely consequential applications like law enforcement.
The future isn’t far when decisions of political and social import will be made by AI assistants. Nonetheless, I can’t help but question the wisdom in placing more trust in machines than we can on a plain old-fashioned human being occupying high office.
Not, at least, until we continue training AI algorithms with that compound gender and racial stereotypes, reinforcing the privilege of those established at the top of the social order.
And herein lies the danger of designing technology with complete disregard to its social repercussions.
Gender bias and racism in machine learning data
It sounds strange to suggest that an algorithm can be stereotypical and show preference towards certain groups in its complex computations.
Does it even make sense to challenge the cold objectivity of mathematical algorithms and have the audacity to hold them guilty of biased judgement?
It turns out that it makes perfect sense. In fact, we have all the reason to doubt the impartiality of our technology.
Let’s take a look at a few examples:
A team of researchers from the University of Virginia found that image datasets used for training machine learning algorithms are characterized by gender bias, containing predominantly male images. Females are outrageously underrepresented in the Microsoft and Facebook cosponsored image dataset as well as University of Washington’s
The researchers found a classic case of gender stereotyping when a visual recognition algorithm trained on ImSitu mislabeled a man standing in a kitchen as “woman”. But sexism isn’t the only sin sophisticated machines are guilty of.
In another research on software that predicts criminal recidivism, it was found that the algorithm gave to black people two times more than white people. A black woman with four juvenile misdemeanors was labelled “high risk”, while a white man with two prior armed robberies was labelled “low risk”. Surely enough, the lady didn’t reoffend, but the man went on to commit a grand theft.
Similar racial and gender discrimination is of Microsoft and IBM, which are much less accurate at identifying black women as compared to white men.
So, what’s going on here?
To put it simply, machine learning algorithms are dependent on the datasets used to train them. If the data is skewed, the software will exhibit a preference towards the group that has majority representation in the dataset. Tech companies are simply feeding their own biases into machines.
The above cases reveal only one of the two ways that machines can be made to discriminate unfairly. These are all instances of bad datasets being used to train good algorithms. But what if the algorithm itself is biased?
If you’re looking for an example of such an algorithm, look no further than Google’s search engine.
The bias of Google
Search “Asian girls” on Google, for instance, and the search results will push scantily clad Asian women in seductive poses on top of any other context Asian girls can be found in. The same goes for Latinas.
(Such search queries used to lead straight to pornographic content, but it bears mention that Google has suppressed much of it now. Nonetheless, a good chunk of search results associated with these queries still lead to hypersexualized representations of women of color).
Google uses predictive technologies to anticipate user intent when a search query is typed. Now, I won’t be surprised if most people actually type in “Asian girls” with sexual amusement as the intent, but Google has a responsibility to display results in a balanced context, rather than blindly .
Correcting these issues might entail a modification of the existing Google algorithm, which at present considers some 200 factors when generating search results for a query. Showing search results untainted by abject discrimination without also undermining the accuracy of comprehending user intent will probably be a challenge, but it is one that deserves Google’s immediate attention.
As it stands, rewarding the privilege of majority on a platform as ubiquitous as Google is a disservice to the struggle for a fairer and equal society.
The case of Google illustrates quite well that both the data and the algorithm (or in other words, the interpretation of the data) need to be free from bias to refine accuracy and improve fairness in AI systems.
The ghost of scientific racism
In a way, the problem of discriminatory technology hearkens back to scientific racism. There’s an of good data leading to bad conclusions in research of comparative capabilities of different human races, which piqued the interest of a few influential scientists in the 19th century.
Chief among these was the American physician Samuel Morton, the founder of craniometry. The professor was known to have the largest collection of human skulls at the time, possessing over 900 skulls from five different ethnic groups which he categorized as Caucasian, African, Native American, Mongolian, and Malay.
From 1839 to 1844, Morton painstakingly conducted his research, measuring the sizes of these skulls and averaging the results for each ethnic group. He found that Caucasians had the largest skull size and Africans were the smallest. Since brain size was believed to be the sole factor that determines intelligence by the contemporary scientific wisdom of the time, Morton had just supposedly found a scientific basis for the intellectual superiority of Caucasians and the inferiority of Africans.
At around the same time, a German anatomist, Friederich Tiedemann, was performing the same kind of craniometric experiments to see how the skulls of different races relate. Curiously, this man reached an entirely different conclusion. Noting the significant overlap between skull sizes of all the measured races, it was obvious to Tiedemann that no significant difference exists between cranial capacity of different ethnic groups, and thus, there are no scientific grounds for racism.
The important point to note here is that the data acquired by both scientists is almost similar and scientifically sound, but it led these men to diametrically opposite conclusions. If Tiedemann focused on averages, he would be tempted to make the same conclusion as Morton. But the measure that seized Tiedemann’s attention was the ranges of skull size for each racial group rather than the averages of each, which happened to be the sole focus of Morton.
This simple change in interpretive approach was clear evidence to Tiedemann of the injustice of slavery and oppression of black populations, while Morton submitted to his possible inherent racist convictions when pronouncing all Africans inferior to Caucasians.
If there’s something to take from this case and apply it to our present scenario, where the interpreters and decision-makers are machines, it is to purge our algorithms free from bias. Otherwise modern technology will only be perpetuating dangerous prejudices akin to scientific racism.
Where do we go now?
The problem with our misbehaving machines, as I see it, stems indirectly from the inequality of social structures around the world, and directly from the lack of diversity in leading tech companies i.e. Google, Facebook, Apple, and Amazon.
It isn’t surprising to see that Google has the out of all major tech companies. In fact, female and minority representation in the tech industry as a whole is abysmally low.
The lack of diversity promotes an environment devoid of any checks against the transmission of discriminatory beliefs (conscious or unconscious) into the products these firms churn out. Anima Anandkuma, a Professor at California Institute of Technology who has previously worked on Amazon’s AI systems says, “Diverse teams are more likely to flag problems that could have negative social consequences before a product has been launched.”
There is arguably no other industry that is more impactful to society than the technology sector. If the firms that comprise this industry are almost entirely represented by white male populations, it is hardly surprising that their products end up being biased against other ethnicities.
As long as tech firms are monopolized by homogeneous groups of people with little to no diversity among them, biases are going to creep their way into the systems and software these firms create.
It is not easy to fathom all the social implications of biased machines. But if there is one thing we can say about society of the future, I bet that it will be heavily influenced by technology with Google, Facebook, and Amazon being the key shareholders in this world. Marching forward into a future where machines are wired to exhibit stereotypical biases could be calamitous and serve only to accentuate the social polarization and inequality in modern society.
To err is human, and that is exactly why we need technology.I just hope that propensity for error remains confined to the human race, for our sake.
