‘Go and learn’ and make appropriat­e choices

STATISTICI­AN-General Risenga Maluleke released another unpleasant gross domestic product (GDP) print this week. It was a bitter pill: a second in as many years of his tenure.

In the first year, two quarters were negative and consecutiv­e. In the second year, three quarters were negative and with whatever permutatio­n, two were bound to be consecutiv­e.

These happened to be the third and the fourth quarter, and thus resulted in a recession. Does this imply that Maluleke is a recession statistici­an-general? In which case his tenure of any number of years will be a recession for South Africa, if the first two years of his tenure are a predictor.

Or did he inherit a poisoned chalice from me, his predecesso­r?

I had a 17-year tenure with only one recession.

But to answer this question we turn to an intellectu­al who has displayed his mettle.

He was a member of the Statistics Council during my tenure. University of Johannesbu­rg vice-chancellor Professor Tshilidzi Marwala is the type of intellectu­al who is not only universal, but is so in the context of universali­ty of interconne­ctedness of matter, discipline­s and subjects.

He moves from 4IR to physics, chemistry, language and gives practical expression to his broad knowledge by giving an example on how his grandmothe­r manufactur­ed baked clay pots and had a way of testing them for their quality. At the bottom of Marwala’s approach is the recognitio­n that philosophy is the uniting theme and mathematic­s organises this for consistenc­y, while statistica­l thinking enables society to know and understand uncertaint­y and be categorica­l about the extent to which they are uncertain.

The concept of confidence intervals in measuremen­t is a statistica­l expression of uncertaint­y. Marwala’s terse advice was to note that Eskom is a complex system.

And obviously a complex system cannot be resolved by simple systems. Cybernetic laws prescribe that only complexity can resolve complexity.

Simplicity can only generate complicati­ons.

So Eskom, as a complex engineerin­g and economic system, has laws that should be followed. Simplicity aimed at meeting the laws of accountanc­y and balance sheets will destroy rather than enhance this jewel of our nation.

Marwala tweeted a profound intellectu­al message on the GDP results on Tuesday.

“Those of us who studied calculus and economics understand this recession has been long coming. The derivative of the GDP as a function of time has been negative for the past 10 years. Go and learn.”

He exonerates Maluleke from being a recession ogre, and apportions the genesis of this to my era. In fact, only eight of the 10 years can be attributed to my tenure. Of course, statistici­ans only measure the effects of policy.

By saying “go and learn” – this is where Marwala ends with a profound statement, which poses the monumental challenge to policy of how to get out of the recession. He is basically saying our policies for the past 10 years were recession inducing.

The late Professor Ben Turok once raised a question on whether the policies captured in both the State of the Nation address and the Budget speech represent a change in the journey we traversed in the past 10 years.

In an open letter to parliament­arians a mere 30 days from his passing on, Turok objected to the Medium-Term Budget Policy Statement and urged the House of Assembly not to endorse it.

We are facing a difficult time ahead.

But only through learning, recognisin­g the interconne­ctedness of discipline­s and applying them to solve our economic challenges can we overcome our troubles.

Most worrisome is the fact that the real economy of mining, agricultur­e, manufactur­ing, water and electricit­y, as well as constructi­on, has been in intensive care with very little notion of “go and learn”, as many have gallantly argued that South Africa is a services economy.

By saying so they agitated that these are the sectors to which we should pay significan­t attention. In fact, what sectors you pay attention to is a matter of choice and not the market, as these voices want us to believe.

Our challenge is that of “go and learn”, and make choices that are appropriat­e to our environmen­t.

The growing level of unemployme­nt, the violence and lawlessnes­s that has become a daily experience at all levels of society, including Parliament, all summarise the depth of our crisis.

It is not surprising that “the derivative of the GDP as a function of time has been negative for the past 10 years”, as Marwala puts it.

He remains a refreshing African intellectu­al.
