Although they purposefully kept the term vague to encapsulate the broad nature of the field, a common argument goes:
“Data science is a science, so you need to be an experienced PhD to be a practioner.”
However, we can clearly see in a few ways that a data scientist doesn’t need an advanced degree, coding expertise, or even a lot of experience:
- The FAANGs, LinkedIn, and most companies don’t ask for advanced degrees.
- No-Code and low-code data science don’t need technical expertise.
- Many leading Data Scientists don’t have advanced degrees.
- Data science bootcamps bring many people into the field without a degree.
- Many PhDs lack the practical experience to work in the field.
1. The FAANGs, LinkedIn, and most companies don’t ask for advanced degrees.
“We’re looking for talent, no matter what their background.”
Indeed, Zuckerberg himself is a drop-out.
Looking at similar roles at LinkedIn, there are asks for a “BS or equivalent experience.”
Like Google, Netflix doesn’t require a degree at all.
2. No-Code and low-code data science don’t need technical expertise.
In the Internet’s early days, building a website required serious technical prowess. Now, no-code tools like WordPress and Wix enable anyone to quickly launch a site.
While the early days of data science required considerable experience across a range of fields, today’s solutions are more “plug-and-play” than ever.
Now, anyone can “turn data into insights,” including making visualizations and predictions on data, without any code.
3. Many leading Data Scientists don’t have advanced degrees.
By now, you might be saying:
“Sure, companies don’t need advanced degrees, but those with advanced degrees make better data scientists.”
This is also wrong.
Kaggle’s top competitor doesn’t have a Ph.D., and Kaggle’s CEO himself admonishes the lack of practical thinking he sees in some data science PhDs:
“Ph.D.s in computer science and statistics spend too much time thinking about what algorithm to apply and not enough thinking about common sense issues like which set of variables (or features) are most likely to be important.”
4. Data science bootcamps bring many people into the field without a degree.
There are many bootcamps or “skills training” courses that teach the skills necessary to be a data scientist, regardless of their academic background.
5. Many PhDs lack the practical experience to work in the field.
Although some point to a Ph.D. as a “holy grail” to enter the field, this couldn’t be further from the truth.
“I had just walked away from 8 years of study and hard work with no plan.”
In 6 months, she taught herself the practical skills to become a data scientist, as any Ph.D. would need to do.
In other words: “A Ph.D. is not enough,” and many books and courses exist to re-train academicians to acquire more practical skills.
- “Stereotypes about the poor quality of academic code.”
- The “academic bubble.”
- “PhDs tend to be bad at marketing themselves.”
- “In academia, people stick to their niche and end up speaking only to others in their discipline.”
You absolutely do not need a Ph.D. to be a data scientist, and while it can help, it can also hold you back.
